conversations.value: 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.

conversations.value: 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.
