Answer:
e
Step-by-step explanation:
Question A: Mai pumped 10 gallons out of her pool. This meaning she is taking out water or a negative sign. She does this in a period of 5 minutes.
The expression should be:
-10 / 5 = -2 | 10 / 5 = 2
so basically either -2 or 2
Question B: Tony added 3 fish to his pond each day for 21 days.
This meaning you have to multiply 3 x 21 or add 3 twenty-one times.
3 x 21 = 63 | 3 + 3 + 3 + 3 + 3 + 3 + 3...
Either method coming to a total of 63.
