A marching band needs $13,500 for a trip. The director told the band members than one-third of the amount that has been raised so far is equal to half of the amount that is still needed. How much more money needs to be raised?
-----
needs 13500
amount raised: x
amount still needed (13500-x)
Equation:
(1/3)x = (1/2)(13500-x)
-------
Multiply thru by 6:
2x = 3*13500 - 3x
5x = 3*13500
x = $8100
----
amt still needed: 13500-8100 = $5400
