Question

A copy machine makes 126 copies in 3 minutes and 30 seconds. How many copies does it make per minute?

Answer 1

Answer: 36 copies per minute

Explanation:

126 copies in 3.5 minutes

We want x number of copies per 1 minute

`(126copies)/(3.5minutes) = (xcopies)/(1minute)`

Cross multiply and we get

126 = 3.5x

Solve for x.

x = 126/3.5

x = 36

36 copies per minute
