A rancher is planning to put up 220 yards of fencing. In the morning she puts up 80 yards, and in the afternoon she puts up 40% of the remaining fence. What percent of the fence did she put up that day?

First, do what all my math teachers told me -- draw a picture.
How many yards were left to put up after 80 yards were finished?
220-80=x
40% * x = y
(80+y)/220 * 100
