Lizzy: Roman and Remy took separate showers. Remy used 1 more gallon than 3 times the number of gallons that Roman used for his shower. Together the boys used 33 gallons of water. How many gallons did Remy use?.
Me: Hmmm, let me think. I think this is the detailed solution:
Let R = Roman's gallons. Remy = 3R + 1. 4R + 1 = 33. 4R = 32. R = 8. Remy used 25 gallons of water for his shower. Final answer: 25.
