Answers:

Sam's current age = 24The mother's current age = 48

=========================================================

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest. You currently have some excess cash. You have the choice of sending Citizens $35,000 now as a partial payment on your loan or purchasing an additional $35,000 of serving supplies such as food containers, cups, and plastic dinnerware for your inventory at a special discount price that is "10% off" your normal cost of these items. (a)

Answers

Answer:

(a) The amount of interest you will save on this loan if you make the partial payment and don't purchase the additional serving supplies is $553.80.

(b) The amount you will save by purchasing the discounted serving supplies and not making the partial payment is $2,946.20.

Step-by-step explanation:

Note: This question is note complete. The complete question is therefore presented before answering the question as follows:

You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest. You currently have some excess cash. You have the choice of sending Citizens $35,000 now as a partial payment on your loan or purchasing an additional $35,000 of serving supplies such as food containers, cups, and plastic dinnerware for your inventory at a special discount price that is "10% off" your normal cost of these items.

(a) How much interest will you save on this loan if you make the partial payment and don't purchase the additional serving supplies?

(b) How much will you save by purchasing the discounted serving supplies and not making the partial payment?

Explanation of the answers is now given as follows:

(a) How much interest will you save on this loan if you make the partial payment and don't purchase the additional serving supplies?

Since an ordinary interest is used, it implies that the total interest amount has to be calculated based on a 360-day year instead of a 365-day year. Therefore, the the interest saved can be calculated as follows:

I_$50K = PRT ........................ (1)

Where,

I_50K = Total Interest on the original $50,000 loan = ?

P = Principal = $50,000

R = interest rate = 9.5%

T = Number of days in the loan period / 360 = (60 + 90) / 360 = 150 / 360 = 0.416666666666667

Substituting the values into equation (1), we have:

I_$50K = $50,000 * 9.5% * 0.416666666666667

I_$50K = $1,979.17

Daily interest on $50,000 loan = I_$50K / Number of days in the loan period = $1,979.17 / 150 = $13.19

Also, we have:

I_PB = PRT ........................ (2)

Where,

I_PB = Innterest on principal balance = ?

P = Principal balance = $50,000 - $35,000 = $15,000

R = interest rate = 9.5%

T = Number of days remaining / 360 = 60 / 360 = 0.166666666666667

Substituting the values into equation (2), we have:

I_PB = $15,000 * 9.5% * 0.166666666666667

I_PB = $237.50

Daily interest on principal balance = I_PB / Number of days remaining the loan period = $237.50 / 60 = $3.96

Daily interest to save = Daily interest on $50,000 loan - Daily interest on principal balance = $13.19 - $3.96 = $9.23

Interest amount to save on the loan = Number of days remaining * Daily interest to save = 60 * $9.23 = $553.80

Therefore, the amount of interest you will save on this loan if you make the partial payment and don't purchase the additional serving supplies is $553.80.

(b) How much will you save by purchasing the discounted serving supplies and not making the partial payment?

This can be calculated as follows:

Discount receivable from purchasing serving supplies = Cost  of serving supplies * Discount rate = $35,000 * 10% = $3,500

Amount to save by purchasing serving supplies = Discount receivable from purchasing serving supplies - Interest payable on loan for the remaining 60 days ................ (2)

Where;

Discount receivable from purchasing serving supplies = $3,500

Interest payable on loan for the remaining 60 days = Interest amount to save on the loan as calculated in part (a) = $553.80

Substituting the values into equation (2), we have:

Amount to save by purchasing serving supplies = $3,500 - $553.80 = $2,946.20

Therefore, the amount you will save by purchasing the discounted serving supplies and not making the partial payment is $2,946.20.

A and B are two similar shapes the area of shape A is 200cm2 calculate the area of shape B

Answers

Answer:

Area of shape B = 312.5 cm²

Step-by-step explanation:

Ratio of Area of A : Area of B = 12² : 15²

Given that area of A is 200 cm², let the area of shape B = x

Therefore:

200:x = 12²:15²

200/x = 144/225

Cross multiply

144x = 200*225

144x = 45,000

x = 45,000/144

x = 312.5 cm²

Area of shape B = 312.5 cm²

The length of a garden is 23m, correct to the nearest metre.

Write down the least possible length of the garden.

Answers

Answer:

22.5m

Step-by-step explanation:

Since it's correct to the nearest metre, it has an interval of ± 0.5

Using rounding concepts, it is found that the least possible length of the garden is of 22.5m.

------------------

If the first decimal digit is between 0 and 4, rounding to the nearest integer, the integer part remains the same.If the first decimal digit is between 5 and 9, rounding to the nearest integer, one is added to the integer part.Thus, in the context of this problem, garden lengths between 22.5 and 23.4 are rounded to 23m, and thus, the least possible length of the garden is 22.5m.

2. The following triangle, ∆, has angle measures as shown.
Step 1: What is the measure of angle C? Show your work.
Step 2: What is the value of x? Show your work.

Answers

Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.  

Angle C= 93 degrees.
