(a)Donna pumped 24 gallons of water out of her pool. This was done over a period of 4 minutes at a constant rate. What was the change in the amount of water in the pool each minute?

Question

For an increase, use a positive number.

For a decrease, use a negative number.

Answer 1

Reduce the fraction to 6/1 (or 6 gallons/minute) by dividing the numerator and the denominator by 4. But since the water is DECREASING, use -6 gallons/minute
