I need urgent help in this math problem! Thanks a lot!?

Kelly invested her savings of $4800. She invested part in mutual funds, at 9% per year, and the rest in GICs, at 10% per year. At the end of the year, the interest from the mutual funds investment was $43 less than the interest from the GIC investment. How much was invested in each type of investment (that is the mutual funds and the GIC) ?

Thanks a lot! Your help is greatly appreciated!

    Let x represent the amount of money invested in GICs.

    Hence, we shall let (4800-x) represent the money invested in mutual funds. (You could do it the other way, too.)

    Now, the rates: 10% and 9%, respectively.

    Set up the equation: 0.1x - 0.09(4800-x) = 43

    0.1x - 432 + 0.09x = 43

    0.19x = 475

    100(0.19x) = 100(475)

    19x = 47500

    Divide each side by 19, get x= 2500

    Hence, 4800-x is 2300

    Mutual fund: 2300$

    GICs: 2500$
