Question. Bobby needs to buy a new pair of fancy shoes. He decides to go to a cobbler and get them handmade. The cobbler charges $250 to make the mold. He then charges $75 an hour for 8 hours to make the shoes. The cobbler agrees to only charge 80% of the cost for work to make the shoes, since it is his first pair of shoes. How much did Bobby pay?
Answer. 730
What step-by-step reasoning justifies that answer?
Reasoning: The cost of labor is 75 * 8 = $600. So Bobby pays 600 * .8 = $480. So that means Bobby pays 480 + 250 = $730.
