A ice cream cone cost $3 plus an additional $0.50 per scoop. James pald a total of $4.50, which equation below
models this situation.
4.50 + 0.50x = 3
0.50x + 3 = 4.50
0.50x = 7.50
3x + 0.50 = 4.50

Answers

Answer:

B: 0.50x + 3 = 4.50

Step-by-step explanation:

James needed an additional 3 scoops so the x would have to be on $0.50. the $3 is what the cone cost so it has to be with the scoop price. $4.50 is the total price of the ice cream so that would be on the other side of the equal sign, resulting in 0.50x + 3 = 4.50

Step-by-step explanation:

Reading the expression:

We're given the sigma notation of a series.

[tex] \mathsf{ \sum _{k = 1} ^{5}(2k - 11) }[/tex]

The variable k is the "index of notation"

The expression can be read as the sum of (2k- 11) as k goes from 1 to 5.

"To generate the terms of a series given in sigma notation, successively replace the index of summation with consecutive integers from the first value to the last value of the index" ~internet

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

Generating the terms of the series:

To generate the terms of the series given on sigma notation above, replace k by 1, 2, 3, 4, and 5 and add the terms, to get the answer to the given notation.

[tex]\mathsf{ \sum _{k = 1} ^{5}(2k - 11) } \\ = \mathsf{ \overline{2(1) - 11} + \overline{2(2) - 11} + \overline{2(3) - 11} } \\ \mathsf{ + \overline{2(4) - 11} + \overline{2(5) - 11}}[/tex]

[tex] = \mathsf{\overline{2 - 11} +\overline{4 - 11} + \overline{6 - 11} } \\ \mathsf{\overline{8 - 11} + \overline{10- 11}}[/tex]

He has a coupon for $10 off any grooming service. He must pay an 8% sales tax, which is applied to the discounted price, and then added to find the total price. Estimate the total amount Paul paid at the dog groomer.

Answers

Answer:

Well since you didn't provide the initial cost im just going to use 100$ as the initial cost.

the service costs 100 dollars minus the coupon of 10 dollars so 90 plus the sales taxes it is (which is 7.20$) it leaves us with a total of 97.20 saving him 10.80$ if he did not use the coupon

A store is instructed by corporate headquarters to put a markup of ​67% on all items. An item costing ​12$ is displayed by the store manager at a selling price of ​8$. As an​ employee, you notice that this selling price is incorrect. Find the correct selling price. What was the​ manager's likely​ error?

please help me in really stuck you would be a huge help

Answers

Answer:

Step-by-step explanation:

12$ = original price (need to add 67% mark up)

12/100 = 0.12 = 1%

0.12 x 67 = $8.04 markup

12 + 8.04 = $20.04 is the correct selling price

the error was accidently not adding the markup ($8.04) to the original price

The difference between 4 times a number and 6 is 18.
O
n = 24
n = 6
n

n = 4

Answers

Answer:

6

Step-by-step explanation:

Let the number be " n ".

4 times a number,

= 4n

The difference between 4 times a number and 6

= 4n - 6

The difference between 4 times a number and 6 is 18,

4n - 6 = 18

4n = 18 + 6

4n = 24

n = 24 / 4

n = 6

The value of "n" that satisfies the equation is n = 6.

Option B is the correct answer.

We have,

To solve the equation "The difference between 4 times a number and 6 is 18," let's define the unknown number as "n."

The difference between 4 times the number and 6 can be expressed as "4n - 6."

According to the given equation, this expression equals 18:

4n - 6 = 18

To solve for "n," we will isolate the variable by performing the necessary algebraic steps:

Add 6 to both sides of the equation:

4n - 6 + 6 = 18 + 6

This simplifies to:

4n = 24

Next, divide both sides of the equation by 4 to isolate "n":

(4n) / 4 = 24 / 4

This simplifies to:

n = 6

Therefore,

The value of "n" that satisfies the equation is n = 6.
