Question 1179983
Jessica has money in two savings accounts. One rate is 6%
and the other is 9%. If she has $550 more in the 9% account and the total interest is $372, how much is invested in each savings account?

let x be invested @ 6%
(x+550) is invested at 9%

6%x+9%(x+550)=372

multiply equation by 100
6x+9x+4950=37200

15x = 32250
x = 2150 @ 6%

2150+550 = 2700 @ 9%

Check
2150*6%+2700*9%= =372
