Question 910026
We have both amts invested 5000 and 3000
we know the total interest earned 550
We know the difference in rates is 3.0%
x*5000-y*3000=550
x=y-0.03
substitute for x
(y-0.03)*5000-y*3000=550
y*5000-0.03*5000-y*3000=550
y*2000-150.0=550
y*2000=150.0+550
y*2000=700.0
y=0.35
y=35.0%
x=0.35-0.03
x=0.32
x=32.0%
check
x*5000-y*3000=550
0.32*5000-0.35*3000=550
1600.0-1050.0=550
550.0=550
