3 ( 5p - p ) - 4 ( 3p - 7 ) =

Answer:

Step-by-step explanation:

Let

x ----> number of tennis balls

y ----> number of tennis rackets

we know that

To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets

In this problem we have

$\frac{x}{y}=\frac{5}{3}$

$x=\frac{5}{3}y$

That means

The number of tennis balls is three-fifths times the number of tennis rackets
