Lizzy: Jonny climbed 1269 stairs last week. Julia climbed 7 less than one-third of that amount. How many stairs did Julia and Jonny climb together?.
Me: Hmmm, let me think. I think this is the detailed solution:
Julia climbed 1269 / 3 - 7 = 416 stairs. Total stairs climbed = 1269 + 416 = 1685 stairs. Together Jonny and Julia climbed 1685 stairs. Final answer: 1685.
