Question

Sara put her dog on a diet and kept track of his weight. At the end of 4 weeks,

she recorded her dog's weight change as -3 1/2 pounds. She noticed her dog lost
the same amount of weight each week. What is the dog's weight change each
week of the diet?

Answer 1

Weight change per week = -0.875 or -7/8

Explanation:

Sara recorded her dog's weight change as -3.5 pounds after 4 weeks of dieting. We know the weight loss is consistent each week, so we need to find out how much the dog loses in one week.

To find out the weight change per week, we can use the formula:

Weight change per week = Total weight change / Total number of weeks

Plugging in the known values:

Weight change per week = -3.5 / 4

Weight change per week = -0.875

The dog loses 0.875 pounds each week.

or -0.875 pounds is the weekly weight change of the dog during the dieting period.
