QUESTION
Carla runs ##4## miles every day. She jogs from home to the school track which is ##3/4## mile away. She then runs laps around the ##1/4-## mile track. Carla then jogs home. How many laps does she run at the school?
10
First express the English statement as a formula. If x is the number of laps run, then ##(1/4)*x + 3/4 +3/4 = 4## Multiply all the terms by 4 ##x + 6 = 16## ##x = 16 -6 = 10##
