Question: James hires a seamstress to fix all his shirts and pants. He has 10 shirts and 12 pairs of pants. It takes 1.5 hours to fix a shirt and twice as long for pants. The tailor charges $30 per hour. How much does it cost? Think carefully first, then make a decision:
It takes 10 * 1.5 = 15 hours to fix his shirts. It takes 1.5 * 2 = 3 hours per pair of pants. So it takes 3 * 12 = 36 hours for the pants. That means in total it takes 15 + 36 = 51 hours. So it cost 51 * 30 = $1530 to fix everything. So the answer is 1530.
