[Question]Wallace's water heater is twice the size of Catherine's water heater. If the capacity of Wallace's water heater is 40 gallons and it's 3/4 full, calculate the total number of gallons of water they both have if Catherine's water heater is also full with water to 3/4 of its capacity.
[Answer]When 3 / 4 full of water, Wallace's water heater has 3 / 4 * 40 = 30 gallons of water. Catherine's water heater capacity is 40 / 2 = 20 gallons. When 3 / 4 full, Catherine's water heater has 3 / 4 * 20 = 15 gallons of water. Together, when 3 / 4 full with water, Wallace's and Catherine's water heaters hold 15 + 30 = 45 gallons of water. The answer is 45.
