Question 324771
"A rancher is planning to put up 220 yards of fencing. In the morning, she puts up 80 yards of fencing. In the afternoon she puts up 40% of the remaining fence. What is the total percentage of the amount of fencing she has put up today?" 
I know the answer is 62%. Every time i work out the answer however, i get 76%. How do you work this problem out?
-------------------------
80 yds in the morning leaves 140 yds
40% of 140 = 56 yds, for a total of 136 yds
136/220 = 0.618 =~ 62%
