You can put this solution on YOUR website! 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?
-----------------
price of ball + tax on ball + price of grapefruit + tax on grapefruit = 515 cents
-----------
Let price of ball be "x" cents
0.07x = 18 cents
x = 257 cents (price of the ball)
----------------------
257.14 + 18 + price of grapefruit = 515
grapefruit = 515 - 275
grapefruit = 240 cents
===========================
Answer:
ball costs $2.57
grapefruit costs $2.40
==========================
