Question

Select and solve the inequality

Ryan is a wrestler trying to make weight. He currently weighs 200 lbs. If he cuts 2 lbs. per week, how many full weeks will it take him to weigh less than 175 lbs.? Choose an inequality below and solve it.



2w+175 <200 -2w+ 200 < 175



-2w+ 200 175 -2w+ 200 > 175



a.) 13 weeks b.) 12 weeks c.) 14 weeks d.) 10 weeks

Answer 1

Explanation:

A.13w, 13 weeks will get him down to 174lbs, 12 weeks would only get him 176lbs, so the minimum/full amount of weeks he needs to get down to less than 175lbs is 13.

Equation:

w=2

13w=26

200-26=174.

Answer 2

Explanation:

The correct option is C More than 12.5 Weeks Let x be the number of weeks, then 200 − 2 x < 175 ⇒ 2 x > 200 − 175 ⇒ 2 x > 25 ⇒ x > 12.5 So, More than 12.5 Weeks is the answer.
