Question 179787
let x and y be the amount invested at 8% and 8.5% respectively
:
x+y=50000........eq 1
.08x+.085y=4120.eq 2
:
rewrite eq 1 to x=50000-y and plug that value into eq 2
:
.08(50000-y)+.085y=4120
:
4000-.08y+.085y=4120
:
.005y=120
:
{{{highlight(y=24000)}}}amount invested at 8.5%
:
{{{highlight(x=50000-24000=26000)}}}amount invested at 8%
