3 families of 4 people shared a vacation rental for 7 days. Everyone uses 1 oversized beach towel a day before getting a new one. The washing machine can hold 14 oversized beach towels per load. How many loads of laundry will it take to wash all the oversized beach towels?
Thoughts? Step-by-step reasoning:
There are 3 families of 4 meaning there are 3 * 4 = 12 people in the vacation rental. They all use 1 oversized beach towel a day so they use 1 * 12 = 12 towels a day. They use 12 towels a day for 7 days so in one week they use 12 * 7 = 84 beach towels. The washing machine can only hold 14 towels and they have 84 towels to wash which means there are 84 / 14 = 6 loads of laundry.
Thus, the answer is 6.
