Question 47658: A man goes into a grocery store and buys a grapefruit and a toy ball. A 7% tax is applied to the price of non-food items. If the total bill is $5.15, including $0.18 in tax on the toy ball, what are the prices of the grapefruit and the ball?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
b = price of ball
g = price of grapefruit
5.15 = .18 + b + g
.07b = .18
b = .18/.07
b = 2.57
5.15 = .18 + 2.57 + g
g = 2.40
check
.07 * 2.57 = .18
.18 = .18
OK
.18 + 2.57 + 2.40 = 5.15
5.15 = 5.15
OK
