Question

An overweight dog is put on a special diet. Use the table to determine the dog’s average weight change per week.

Week Number Weight Change (oz)

1 –1.5

2 2.2

3 –0.8

4 –1.6

5 –0.6

Answer 1

The average weight change per week for the overweight dog on the special diet is approximately -0.14475 pounds.

Step-by-step explanation:

The best unit to measure the weight of a large dog is pounds. In the table, the weight change is given in ounces. To convert the weight change from ounces to pounds, divide each value by 16 since there are 16 ounces in a pound.

1. Week 1: -1.5 ounces ÷ 16 = -0.09375 pounds
2. Week 2: 2.2 ounces ÷ 16 = 0.1375 pounds
3. Week 3: -0.8 ounces ÷ 16 = -0.05 pounds
4. Week 4: -1.6 ounces ÷ 16 = -0.1 pounds
5. Week 5: -0.6 ounces ÷ 16 = -0.0375 pounds

Therefore, the average weight change per week for the overweight dog on the special diet is approximately:

• -0.09375 + 0.1375 - 0.05 - 0.1 - 0.0375 = -0.14475 pounds
