Question

A machine produces 540 parts every of an hour. The person running the machine says that the machine should produce 720 parts in each 8-hour day. Is the answer reasonable? Why or why not?

1) No. The machine will produce 4,320 parts per day, since 540 × 8 = 4,320.
2) No. The machine will produce 3,240 parts per day, since 405 × 8 = 3,240.
3) No. The machine will produce 720 parts in 1 hour, not in 1 day.
4) No. The machine will produce 405 parts per day.
5) Yes. The machine produces 540 parts in of an hour.

Answer 1

A machine produces 540 parts every of an hour. The person running the machine says that the machine should produce 720 parts in each 8-hour day. No. The machine will produce 3,240 parts per day, since 405 × 8 = 3,240. So, the correct answer in option 2.

Explanation:

The correct answer is:

2) No. The machine will produce 3,240 parts per day, since 405 × 8 = 3,240.

The reason is that the machine produces 540 parts every hour, and there are 8 hours in a day. So, the total number of parts produced in a day is 540 * 8 = 4,320. Therefore, the answer is not reasonable because the machine should produce 4,320 parts in each 8-hour day, not 3,240.
