Debra invested her savings in two investment funds.
The amount she invested in Fund A was 3 times as much as the amount she invested in Fund B.
Fund A returned a 4% profit and Fund B returned a 5% profit.
How much did she invest in Fund A, if the total profit from the two funds together was 2280?
Let x = amt invested in fund B
3x = amt invested in fund A
Total interest equation
.05x + .04(3x) = 2280
.05x + .12x = 2280
.17x = 2280
x = 13411.76 in fund B
3(13411.76) = $40,235.29 in fund A
Check these values, find the total interest
.04(40235.29) + .05(13411.76) =
1609.41 + 670.59 = 2280, confirms our solutions
