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

Question

Week Number Weight Change (oz)
1 –1.5
2 2.2
3 –0.8
4 –1.6
5 –0.6

Select the correct answer.
0.46 ounces per week
–2.3 ounces per week
–0.46 ounces per week
0.58 ounces per week

Answer 1

To calculate the average weight change per week, we first need to find the total weight change over the 5 weeks.

Total weight change = (-1.5) + 2.2 + (-0.8) + (-1.6) + (-0.6) = -2.3 ounces

Now, to find the average weight change per week, we divide the total weight change by the number of weeks:

Average weight change per week = Total weight change / Number of weeks
= -2.3 ounces / 5 weeks
= -0.46 ounces per week

Therefore, the correct answer is:
-0.46 ounces per week
