A few years ago, Mr. Cromleigh had been dying to go to a Taylor Swift concert. The tickets cost $65 each and he wanted to get 2 (for him and his mom of course!) He had been saving his allowance from his mom every week. He started with $40 and his mom would give him $10 a week to do chores around the house. How many weeks did it take him to earn the money to go to the concert?
It took him ------------------------------------ weeks until he was at the concert singing "Shake it Off" with his mom!
