Question

Cookies are on sale! Today each cookie costs $0.75 less than the 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 the normal price of each cookie.

Answer 1

Well first to find out how much the cookies are on sale you do
$2.80/7= 0.40$
So on sale each cookie is 40 cents each, now to figure out the normal price add 75 cent to the sale price so:
$0.40 + 0.75 = 1.15$
So that gives us $1.15
So the normal price for the cookies is $1.15 and the sale price is $0.40 cents
