Question

The weight, w, of a person on a diet plan is equal to the original weight of the person, a, minus the product of the number of pounds lost per week, r, and the number of weeks, x, of the diet plan. susy is starting a diet plan with a current weight of 187 pounds. she expects to lose 3 pounds per week, until reaching her healthy weight. if susy loses the weight at the expected rate, how much will she weigh, in pounds, 12 weeks from the start of the diet plan?

Answer 1

Susy will weigh 151 pounds 12 weeks from the start of the diet plan.

Step-by-step explanation:

To find out how much Susy will weigh 12 weeks from the start of the diet plan, we can use the formula w = a - r*x, where w is the weight, a is the original weight, r is the rate of weight loss, and x is the number of weeks on the diet plan.

Given that Susy's current weight is 187 pounds and she expects to lose 3 pounds per week, we can substitute these values into the formula: w = 187 - 3*12.

Simplifying the expression, we get w = 187 - 36, which equals 151 pounds.

Therefore, Susy will weigh 151 pounds 12 weeks from the start of the diet plan.
