Question 1099892
Total amount of money invested: $2500
x+y=2500,
Total yearly interest for the two accounts is: $113
0.02*x+0.09*y=113
x=2500-y
Substitute for x
0.02*(2500-y)+0.09*y=113
Multiply out
50-0.02*y+0.09*y=113
Combine like terms.
0.07*y=63
Isolate y
y=$900.00 at 9% earns $81 interest
x=2500-y
Calculate x
x=$1600.00 at 2% earns $32 interest
Check
0.02*1600+0.09*900=113
32+81=113
113=113
