Mrs lao bought 5 blouses and 6 skirts for $108. Three skirts cost as much as 2 blouses. How much did she pay for the 6 skirts?
3s = 2b
s = 2b/3
5b + 6s = 108
5b + 6(2b/3) = 108
5b + 4b = 108
b = 12
then s = 8
6 skirts = 48
s = 2b/3
5b + 6s = 108
5b + 6(2b/3) = 108
5b + 4b = 108
b = 12
then s = 8
6 skirts = 48
