Question

At the start of the month, the counter on the copy machine reads 6,583. At the end of the moth, it reads 82,110. The copies cost 1 1/3 cents a piece. What was the approximate total cost of the copies for this month?

Answer 1

$1007.03

Explanation:

You want the cost of copies for the month at 1 1/3 cents each if the copy counter ran from 6583 to 82110 during the month.

Number of copies

The number of copies made is the difference in counter readings:

82110 -6583 = 75,527 . . . . . copies made

Cost

Each costs 1 1/3 = 4/3 cents, so the cost of these copies is ...

(75,527 copies) × (4/3 cents/copy) = 100702 2/3 cents ≈ 100703 cents

There are 100 cents in a dollar (or other currency unit), so the cost is about ...

(100703¢)/(100¢/$) = $1007.03

The total cost of copies for the month is about $1007.03.

Additional comment

The currency unit is not specified in this problem. There are a number of world currencies in which the smallest denomination is 1 cent. The US dollar, the Euro, and the Aruban Guilder are some of them.
