To solve this problem, you essentially just have to compare some quantities; the last thing you say is that George can get 50 feet of hose for $12.99 and he needs 33 x 3 = 99 feet of hose for his garden. If George can only buy hose in 50 Ft. bundles, then he needs 2 bundles to get his 99 feet. This will cost 2 x $12.99 = $25.98, so George doesn't have quite enough money to do it. I suggest he borrow 98 cents though, since he's just so darn close. If the hose is sold by the foot (which may not be a valid assumption, since I think it's usually sold in bundles), this is $12.99 / 50 = 25.98 cents per foot. At this price, 99 feet will cost $25.72, so he still doesn't have quite enough money, but he's closer. Thanks for the question! -K
