Question

Colby’s art class is 50 minutes. She spends 21 minutes cutting paper and the rest of the time making a collage. How much time did Colby spend making her collage?

Answer 1

29 minutes spent on the collage
50-21=29

Answer 2

Colby spends 29 minutes making her collage.

50 is the total amount of minutes and 21 minutes is a part of that total.

This means we have to subtract.

50 - 21 = 29.
