Answer this question:Matt and Tom both walk up the stairs of the library. Matt goes up the stairs 20 steps per minute. Tom goes up the stairs 5 steps per minute more than Matt. If Matt has reached 220 steps above the entrance, how many steps will Tom have gone up by that time?
Matt would have walked for 220 / 20 = 11 minutes. Tom would have gone up by 11 * 5 = 55 steps more. Tom would have gone up by 220 + 55 = 275 steps.
The answer is 275.

Answer this 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?
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.
The answer is 1530.
