Question

Benny earns $12.00 per hour as a life guard. He earns a bonus of $75.00 for taking a training course. How many hours must Benny work to earn at least $399.00?

Answer 1

It would take him 27 days to earn $399

Answer 2

Hi!

Let's subtract the $75 Benny earns for taking a training course, because he's already got that:

399 - 75 = 324

Now, divide that by the amount of money he's paid per hour:

324 ÷ 12 = 27

Benny must work at least 27 hours.
