Answer:
Subtract 3 from 8, then divide 75 by 5.
Explanation:
First, subtract 3 from 8 since she finished 3 already.
8-3=5
This means that Sumi has 5 more pots to make. Since she has 75 minutes left, and she wants to finish all the pots in the same amount of time, we can divide 75 by 5.
75/5=15
Sumi should finish each pot in 15 minutes.
