Question

Andrew has $20 saved and is working for $8

an hour. How many hours does he have to
work to save a total of at least $140?

Answer 1

15 hours

Explanation:

Firstly, Andrew has 20$ saved, right? So we should minus that by our goal, $140.

140-20=120

That leaves us with $120 to earn. Andrew works for $8 an hour. So we should divided 120 by 8 to get the number of hours he needs to work to get $140.

120÷8=15 hours

Which means that Andrew has to work for 15 hours to get a total of $140.
