  1. @spots Well, if you consider that textbooks cost an arm and a leg, let's assume each textbook averages $80. Since legs and arms are equally important, this puts the cost of each at $40. Jerry paid $10 which is 0.25 limb, and Jimmy paid $12 which is 0.3 limb. But where did they get this money if they have none of their own? Why, they asked their friend Sarah of course. Sarah has no money either, but she does have a dog with legs to spare. Let's assume she originally had a fully healthy dog with four complete legs, this is 4 limb. In other to get the $22 she had to exchange 0.55 leg for equivalent value. However, the place of exchange charged a 10% tax, so she actually had to exchange 0.55/0.9 = 0.6111 (rounded) leg. Therefore her dog has 3.3889 legs.
