Given :
Cookies are on sale, the price of each cookie is reduced by $0.75.
You buy 7 cookies, it will cost $2.80.
To Find :
The cost of cookies before sale.
Solution :
Let the normal price of each cookies be x.
Price of each cookie is reduced by $0.75.
The price of 7 cookies $2.80 in sale.
The equation for the normal price of each cookie would be
7(x - 0.75) = 2.80
(x - 0.75) = 0.40
x = 0.40 + 0.75
x = 1.15
The normal price of each cookie was $1.15
