Answer 1

C =
`(2.8)/(7) + 0.75`

$1.15

Explanation:

Here is the complete question :

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). Find he normal price of each cookie.

the discounted price of one cookie = total sales price of 7 cookies / 7

$2.8 / 7 = $0.4

it was stated in the question that the sales price is $0.75 less than normal price. Thus the normal price of the cookie = $0.4 + $0.75 = $1.15

the equation :
`(2.8)/(7) + 0.75`
