On Sunday morning, Pugsley and Wednesday are trading pet spiders. If Pugsley were to give Wednesday two of his spiders, Wednesday would then have seven times as many spiders as Pugsley does. But, if Wednesday were to give Pugsley four of her spiders, Pugsley would now have four fewer spiders than Wednesday had before they traded. How many pet spiders does Pugsley have before the trading game commences?
Pick one:
A) 2  B) 4  C) 6  D) 8  E) 10
If Pugsley were to give Wednesday two of his spiders, Wednesday would then have seven times as many spiders as Pugsley does:   (w + 2) = 7(p - 2)   If Wednesday were to give Pugsley four of her spiders, Pugsley would now have four fewer spiders than Wednesday had before they traded:   p + 4 = w - 4   Solving gives p = 4 and w = 12.   Answer: 4.
