Answer 2

The cost to make 85 copies will be $34.

What are equivalent Ratios ?

Two or more ratios are called Equivalent when they have the same value when reduced to the simplest form.

It is given ion the question that

At a local print shop, 20 copies can be made for $8.

cost to make 85 copies = ?

So to determine the cost

It is known that the copies and the rates are in ratio

So the ratio is 20:8

or 10:4

or 5 :2

20:8 , 10: 4 , 5:2 are all equivalent ratios.

The ratio of 85 copies and x cost is

85:x , this is equal to any of the equivalent ratios

85 : x = 5:2

x = 85*2 /5

x = $34

Therefore $34 will be the cost of 85 copies.
