Question

Ethan is printing some materials for a meeting if the printing of the first copy cost 1 1/2 dollars and other copies cost 4/5 of a dollar each to print how much will it cost if he is making 13 copies?

Answer 1

$11.10

Explanation:

The last 12 copies cost $0.80 each, so the price of those plus the $1.50 price of the first copy will be ...

$1.50 +12×0.80 = $1.50 +9.60 = $11.10

Ethan's printing job will cost $11.10.
