Q. The house Trevor's family lives in has 66 people (including Trevor) and 33 bathrooms. In the past month, each person showered for an average of 480480 minutes and used an average 7272 liters of shower water (over the entire month). Water costs 0.200.20 dollars per liter.\newlineHow much money did Trevor's family spend, in total, on shower water in the past month?\newline\square dollars\text{dollars}
  1. Calculate total shower water: Calculate the total amount of shower water used by Trevor's family in the past month.\newlineEach person used 7272 liters of water, and there are 66 people in the family.\newlineTotal water used = 7272 liters/person ×\times 66 people
  2. Perform calculation: Perform the calculation from Step 11.\newlineTotal water used = 72liters/person×6people=432liters72 \, \text{liters/person} \times 6 \, \text{people} = 432 \, \text{liters}
  3. Calculate total cost: Calculate the total cost of the water used for showering.\newlineWater costs 0.200.20 dollars per liter, so we multiply the total water used by the cost per liter.\newlineTotal cost = Total water used ×\times Cost per liter\newlineTotal cost = 432432 liters ×\times 0.200.20 dollars/liter
  4. Perform cost calculation: Perform the calculation from Step 33.\newlineTotal cost = 432liters×0.20dollars/liter=86.4dollars432 \, \text{liters} \times 0.20 \, \text{dollars/liter} = 86.4 \, \text{dollars}
