You can put this solution on YOUR website! x and 34,000-x
.12x-.05(34000-x)=170
.12x-1700+.05x=170
.17x=1870
17x=187000
x=$11000@12%=$1320
32000-x@=$23000@-5%=-$1150
The gain is $170.
$11,000 in fund
$23,000 in stocks.
------------------------
S= 4LW+ 2WH; S= 84, L= 9, W=2
84=4*9*2+4W=72+4H
12=4H
H=3
-----------------------
A=9x
B=x
Their sum is 10x=20,000,000
x=2 million
9x=18 million, which is 9 times as much and the two add to 20 million.
