Answer:

Number of minutes is 80 minutes
Step-by-step explanation:
Given
The attached table
Calculating the number of copies the machine can make in a minute
Represent number of minutes with m and number of copies with n
First, we need to calculate the ratio of m to n
<em></em>
<em></em>
<em>When m = 5; n = 325</em>


<em>When m = 10; n = 650</em>


<em>When m = 15; n = 975</em>


When we continue for other values of m and n, the ratio remains the same;
So; we make use of
to determine the relationship between m and n
Substitute 65 for Ratio

Multiply both sides by m



This implies that, you have to multiply the number of minutes by 65 to get the number of copies
Calculating the number of minutes to print 5200 copies;
In this case;
Ratio = 65 and n = 5200
So;
becomes

Multiply both sides by m


Divide both sides by 65



<em>Hence; number of minutes is 80 minutes</em>
