Question

Roy weighs 150 pounds and plans to lose

Answer 1

Answer:

50 weeks

Explanation:

Given that :

ROY:

Initial weight = 150 pounds

Weight loss per week = 1.5 pounds

LUIS:

Initial weight = 200 pounds

Weight loss per week = 2.5 pounds

Let x = Number of weeks

Number of weeks when both Luis and Roy will weigh the same:

150 - 1.5x = 200 - 2.5x

-1.5x + 2.5x = 200 - 150

x = 50

Hence, Roy and Luis will weigh the same after 50 weeks
