Jake's band played songs at three different parties. At the first party they played one-fourth as long as they did at the second party, which was one-half as long as the third party. If they played for 7 minutes at the first party, how many minutes did they play at the third party?

wait i'm doing
OpenStudy (texaschic101):
a = 1st party
b = 2nd party
c = 3rd party
a = 7 minutes
a = 1/4b
7 = 1/4b
7/(1/4) = b
7 * 1/4 = b
28 = b
b = 1/2c
28 = 1/2c
28/(1/2) = c
28 * 2/1 = c
56 = c
