Question: Leila spent 3/4 of her savings on make-up and the rest on a sweater. If the sweater cost her $20, what were her original savings?
Answer with step-by-step thinking: If Leila spent 3 / 4 of her savings on make - up, this means she spent 1 - 3 / 4 = 1 / 4 of her savings on a sweater. Let S be her original savings. If the sweater cost $20, this means 1 / 4 * S = $20. Thus S = $20 * 4 = $80.
So the answer is 80.

Question: Alex has not washed his clothes for a month; 18 shirts, 12 pants, 17 sweaters, and 13 jeans are waiting to be washed. Alex's washing machine can wash a maximum of 15 items per cycle. Each cycle takes 45 minutes. How many hours will it take the washing machine to wash all the clothes?
Answer with step-by-step thinking: Alex will wash 18 + 12 + 17 + 13 = 60 items. With 20 items per wash cycle, Alex will wash the clothes in 60 / 15 = 4 cycles. With 45 minutes per cycle, the washing machine will take 45 * 4 = 180 minutes to wash the clothes. As 1 hour has 60 minutes, the washing machine will take 180 / 60 = 3 hours to wash the clothes.
So the answer is 3.
