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

We know that 7 cookies at the current price (75 cents less than normal) will cost $2.80.

Thus, we can set up the equation 7(c - .75) = 2.80
Now, let's solve for c.

c - .75 = .4
Add .75 to get:

c = 1.15
