Aron spends 30 minutes/day three times a week vacuuming and 20 minutes/day 2 days a week dusting. How much time does he spend cleaning total each week? Give me reasons, before answering the question
First find the total time Aron spends vacuuming: 30 minutes / day * 3 days / week = 90 minutes / week. Then find the total time Aron spends dusting: 20 minutes / day * 2 days / week = 40 minutes / week. Then add those two times to find Aron's total cleaning time per week: 90 minutes / week + 40 minutes / week = 130 minutes / week. So the final answer is 130.
