The machine can produce 22 400 copies in 7 hours.

In 7 hours 22 400 copies were produced.

In 1 hour 22 4000/ 7 would be produced.

Therefore in 21 hours (22 400 / 7) * 21 will be produced.

Solving this = 22 400 * 3.

= 67 200 copies.

The copy machine in your office can produce 22,400 copies in 7 hours. How many copies can it produce in 21 hours?
