Answer 1

Answer: The equation to determine the normal price of each cookie is : 7(c-0.75) = 2.80

Step-by-step explanation:

Hi, the correct form of the answer is:

Cookies are on sale! Today each cookie costs $0.75 less than normal price. Right now if you buy 7 of them it will only cost you $2.80!

Write an equation to determine the normal price of each cookie (c)

So, to answer this question we have to analyze the information given:

The normal price of a cookie is "c", if each cookie cost $0.75 less than the normal price, it means:

(c -0.75) = today’s price of a cookie

If you buy 7 of them, 7(c-0.75), it will cost $2.80.

Mathematically speaking:

7(c-0.75) = 2.80

Solving for c  :

7c - 5.25 =2.80

7c = 2.80 +5.25

7c = 8.05

c = 8.05/7= 1.15

The normal price of each cookie is $1.15.
