A shirt, a video game, and a book together cost $170. The shirt costs $59. The video game costs $36 more than the shirt. How much less does the book cost than the video game?

Answer 1

s = price of shirt

v = price of video game

b = price of book

A shirt, a video game, and a book together cost $170 means:

s + v + b = 170

The shirt costs $59 means:

s = 59

The video game costs $36 more than the shirt means:

v = s + 36 = 59 + 36 =$95

Put this values in equation:

s + v + b = 170

59 + 95 + b = 170

154 + b = 170

Subtract 154 to both sides.

b = $16

v - b = $95 - $16 = $79

The book cost $79 less than the video game.
