Consider the question. To make a shed in his backyard, Tom needs 1000 bricks. He can buy half of the bricks for 50% off of $.50. The other Half he needs to pay full price. How many dollars does Tom spend?
 If the answer is '375'; explain the reasoning:
Tom can buy 1000 / 2 = 500 for half price. He will spend $.50 / 2 = $.25 on the half - priced bricks. Thus, he will spend 500 * $.25 = $125 on the half - priced bricks. He will spend 500 * $.50 = $250 on the full - priced bricks. Thus, he will spend $125 + $250 = $375 total.
