Let x = the amount of money he invests at 9%
and y = the amount of money he invests at 3%
y = x - 1400
0.09x + 0.03y = 198
x - y = 1400
9x + 3y = 19800
3x - 3y = 4200
9x + 3y = 19800
12x = 24000
x = 2000
y = 600
$2000 invested at 9% interest
and $600 invested at 3% interest.
Expenditures are negatives do I'd use -42.50
