First find the total time Aron spends vacuuming: 30 minutes/day * 3 days/week = <<30*3=90>>90 minutes/week

Then find the total time Aron spends dusting: 20 minutes/day * 2 days/week = <<20*2=40>>40 minutes/week

Then add those two times to find Aron's total cleaning time per week: 90 minutes/week + 40 minutes/week = <<90+40=130>>130 minutes/week
