A bookstore marks up the price of a book by 40% of the cost from the publisher. Therefore, the bookstore's price to the student, P(x) (in $) after a 7.5% sales tax, is given by P(x) = 1.075(x + 0.40x), where x is the cost of the book from the publisher. Evaluate P(60) and interpret the meaning in the context of this problem
Answer:
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Step-by-step explanation:
Solution:
The cost of book from publisher = 40%
Sales tax = 7.5%
Price of books to the student = p(x) = 1.075x + 0.40x
Where, x is cost of book.
P (60) =?
We know that,
P(x) = 1.075 + 0.40
= 1.475%
=148
Given, Cost of book, x = 60
P (60) = 148 – 60
= 88
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.

The average weight of the top 5 fish at a fishing tournament was 13.3 pounds. Some of the
weights of the fish are shown in the table.
Answer:
15.4 lbs
Step-by-step explanation:
Since the average of the top five is 13.3 this says that:
total weight of all the fish / 5 = 13.3 lbs
Therefore, the total weight of all five fish is equal to:
13.3 * 5 = 66.5
With this number, I subtracted all the other weights and found that the missing weight was:
15.4lbs.
Therefore, Wayne S. had the biggest fish weighing 15.4lbs
Answer:
15.4
Step-by-step explanation:
(14.2 + 13.4 + 12.1 + 11.4 + X) / 5 = 13.3
(51.1 + X) / 5 = 13.3
Cross:
51.1 + X = 66.5
then X = 66.5 - 51.1
= 15.4
Crystal baked 54 muffins for her family and friends. Her friends take 1/6 of the muffins. How many muffins does she have left? Of the muffins that she has left, her family took 2/5 of them. How many muffins did her family take? After her friends and family have taken their muffins, Crystal eats 1/3 of what is left. How many muffins did Crystal eat?
Answer:
she has 45 muffins left
her family took 18 muffins
crystal ate 9 muffins
Step-by-step explanation:
54 × 1/6 = 9
54 - 9 = 45
45 x 2/5 = 18
45 - 18 = 27
27 x 1/3 = 9

A phone company has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 410 minutes, the monthly cost will be $71.50. If the customer uses 720 minutes, the monthly cost will be $118. Find a linear equation for the monthly cost of the cell plan as a function of x, the number of monthly minutes used.
Answer:
Linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]
Step-by-step explanation:
Let u denotes a flat monthly fee and v denotes amount charged per minute.
As the monthly cost is $71.50 if a customer uses 410 minutes,
[tex]71.50=u+410v[/tex] (i)
As the monthly cost is $118 if a customer uses 720 minutes,
[tex]118=u+720v[/tex] (ii)
Subtract (i) from (ii)
[tex]118-71.50=u+720v-u-410v\\46.5=310v\\v=\frac{46.5}{310}\\ v=0.15[/tex]
Put [tex]v=0.15[/tex] in (i)
[tex]71.50=u+410(0.15)\\71.50=u+61.5\\u=71.50-61.5\\u=10[/tex]
As x denotes the number of monthly minutes used,
linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Sally and Anne went to the movies. They each purchased a drink. They also bought one popcorn and one veggie cup to share. Each woman's total is modeled with this expression: 9+1.34+1/2(3.50+1.74) How would you simplify the expression? Explain your steps.
Answer:
12.91
Step-by-step explanation:
We are told that Each woman's total is modeled with this expression:
9 + 1.34 + 1/2(3.50 + 1.74)
To solve this we will use the BODMAS acronym.
So the first operation will be to solve what's in the bracket to give;
9 + 1.34 + 1/2(5.14)
Let's now carryout the multiplication of the bracket to give;
9 + 1.34 + 2.57
Using the addition operation now gives us: 12.91
Answer: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.

Answer:
Step-by-step explanation:
3) diameter of penny = 19 mm
r = 19/2 = 9.5 mm
Area of penny = πr²
= 3.14 * 9.5 * 9.5
= 283.385
= 283.39 mm²
Diameter of nickel = 21 mm
r = 21/2 = 10.5 mm
Area of nickel = πr²
= 3.14 * 10.5 *10.5
= 346.185
= 346.19 mm²
346.19 - 283.39 = 62.8 mm²
Area of Canadian nickel is greater than Canadian penny by 32.6 mm²
4) r = 12 mm
Area of circle = πr²
= 3.14 * 12 * 12
= 452.16 mm²
5) r = 20 cm
Area of circle = πr²
= 3.14 * 20 * 20
= 1256 cm²

Step-by-step explanation:
The sum of two numbers is 4 times their difference. If one exceeds the other by 8, what are the numbers?
Answer:
12, 20
Step-by-step explanation:
Let the two numbers be x and y, where x > y
According to the given information:
x + y = 4(x - y)
x + y = 4x - 4y
y + 4y = 4x - x
5y = 3x
[tex] y = \frac{3}{5}x.... (1)[/tex]
Since, one number exceeds the other by 8.
[tex] \implies x = y + 8\\\\
\implies y = x - 8.....(2)\\\\[/tex]
From equations (1) & (2)
[tex]x - 8 = \frac{3}{5} x \\ \\ 5(x - 8) = 3x \\ \\ 5x - 40 = 3x \\ \\ 5x - 3x = 40 \\ \\ 2x = 40 \\ \\ x = \frac{40}{2} \\ \\ \huge \purple{ \boxed{\implies x = 20}} \\ \\ \implies \: y = x - 8 = 20 - 8 \\ \\ \huge \pink{ \boxed{ \implies \: y = 12}}[/tex]
Harper knows he is 100 yards from school. The map on his phone shows that the school is 1/3 inch from his current location. If Harper’s current location is 3 inches from home on the same map, how far is Harper from home?
Helpppp
Answer:
4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
Step-by-step explanation:
The actual distance of the Harper from the school = 50 yards. According to the map, the distance from the school = 34 inches. We could say 34 inches represents 50 yards. So, 1 inch could be represented by 50/34 = 25/17 yards. In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately. Therefore, Harper from home is 4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
