<PRE><B>Question 389335</B>
Homer Simpson weighs 400 pounds. He is on a diet to lose 5 pounds each week. Barney Gumble weighs 322 pounds. He is on a diet to lose 3 pounds each week. How long will it take for them to weigh the same?
.
Let w = weeks of dieting
then

400-5w = 322-3w

400 = 322+2w

78 = 2w

39 weeks = w
