Question

jason weighs 200 pounds. He wants to weigh at most 175 pounds. If he loses 2 pounds per week on his new diet, how long must he stay on his diet to reach his goal

Answer 1

He needs to loose 25 pounds, if he loses 1 pounds per week, then he will need 25 weeks, now he loose 2 pounds per week, so he needs half the time to achieve his goal. Round your answer to the next highest integer.

Answer 2

w represents number of weeks

 

He want to lose at least 25 pounds (200 - 175) at 2 pounds per week.

 

2w ≥ 25        divide both sides by 2

w ≥ 12.5

 

He must be on his diet for at least 12.5 weeks.
