Copy center charges .08 per page for machine-fed copies and .20 per page for hand-fed copies. If Logan's bill for 80 copies of his script is 13.00

Let x be the number of machine copies

then 80-x must have been hand- fed copies

The total cost would be .08x + .2 (80-x)

But we know the total cost = 13

.08x + .2 (80-x) =13

Multiplying both sides by 100 to get rid of decimals gives

 8x + 20 (80-x) =1300

8x + 1600 – 20x = 1300

-12x                    = -300

x= 300/12 = 25

There were 25 machine copies and 80-25 = 55 hand- fed copies

(check that this gives a total bill of 13 dollars yourself)
