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.
----------------------
Investment Eq::: m + G = 4800
Interest Eq:::: 9m = 10G - 4300
-------
Rearrange:
9m + 9G = 9*4800
9m -10G = -4300
----
Subtract and solve for "G":
19G = 47500
G = $2500 (amt. invested in GIC's)
-------
Solve for "m":
m + G = 4800
m = 4800-2500
m = $2300 (amt. invested in mutuals)
