Question

The ratio of the cost of a tennis racket to tennis balls is 18:1. If a can of balls cost $5.35, what is the cost of the racket?

Answer 1

Answer:

The cost of the tennis racket will be: $ 96.3

Step-by-step explanation:

The ratio of the cost of a tennis racket to tennis balls is 18:1.

This means that , if the cost of tennis balls is: $ x

Then the cost of the tennis racket will be: $ 18x

Now, it is given in the question that:

a can of balls cost $5.35.

This means that : x= 5.35

Hence, the cost of the racket will be:

cost of racket= 18×5.35

i.e.

cost of racket= $ 96.3

Answer 2

Racket to ball ratio is 18:1 ; 18 is racket and 1 is ball. Ratio can also be shown as fraction 18/1.
Ball cost 5.35. If ball in ratio is represented by the 1, then ball cost is on denominator. r will represent racket cost.
r/5.35
Equation:
18/1 = r/5.35
Cross multiply
96.3 = r

Racket cost is $96.30
