Lizzy: Jackson wants to improve his endurance running. His goal is to start by running 3 miles a day the first week, then spend the next four weeks running one additional mile/day each week. How many miles is Jackson running each day at the end of this exercise program?.
Me: Hmmm, let me think. I think this is the detailed solution:
First, figure out how many additional miles Jackson is running after four weeks: 4 weeks * 1 extra mile / week = 4 extra miles. Then add the 4 extra miles to the 3 miles he initially ran: 4 miles + 3 miles = 7 miles. Final answer: 7.
