how do you solve this
I keep trying and I keep getting the wrong answer. I keep getting x=19000 and that is not correct
.10=.9(x/15000)+.14[(1x)/15000]

Math 
Reiny,
multiply each term by 15000
1500 = .9x + .14(1x)
expand, collect like terms ...
I get x = 1973.5
which when substituted into the original equation will satisfy it.
