Question

A tennis racket costs $12 more than a hockey stick. If the price of the two is $31,
find the cost of the tennis racket.

Answer 1

Answer:

The cost of tennis racket is 19 $

Answer 2

Let,

• Cost of hockey stick = x

• Cost of tennis racket = x+12

⇒ Cost of both = x+x+12

⇒ 31 = x+x+12

⇒ 31 = 2x+12

⇒ 2x = 31-12

⇒ 2x = 19

⇒ x = 19/2

⇒ x = $ 9.5

∴ Cost of hockey stick (x) = $ 9.5

∴ Cost of tennis racket (x+12) = $ 21.5
