Question

Roy weighs 150 pounds and plans to lose 1.5 pounds a week. Luis weighs 200 pounds and plans to lose 2.5
pounds a week. Which equation shows when Roy and Luis will weigh the same?
Use x for the number of weeks.

Answer 1

Roy: y=150-1.5x

Luis: y=200-2.5x

150-1.5x=200-2.5x

150=200-x

-50=-x

50=x

So in 50 weeks, Roy and Luis will weigh the same at 75 pounds each.
