Turbo · Answer 1

50+75 = 125$

125 divided by 65 = 1.92

1.92 rounds up to 2, so it would take approximately 2 hours.

If you need to find an exact number then we need to find a number greater than 125 that both 50 and 65 can fit into.

125 + 50 + 50 + 50 + 50 = 325

325 divided by 65 = 5

So it would take 4 hours of work with Abe to cost 325 and 5 hours of work with the other service.
