Asked by Valerie

Shelly is working 250 math problems and she wants to finish in 6 days. If she works the same number of problems each day for 5 days how many problems will she have left to work on day 6?
Answered by Steve
If she does n problems on each of the first 5 days, then that makes 5n.

So, she will have 250-5n left on the 6th day.
