Question

Anna earned some movie money by shoveling the driveway. sHe shoveled 1/5 of the driveway after school, then 1/2 of what was left after she did her math homework, then finished the remaining 200 square feet after supper.
Ms. Sue
And your question is?

presumably we want to find the original area to be shoveled. If that was x, then

x(1/5 - 2/5) = 200
