I invested a certain amount of money at 4% and an amount $2000 less than the first amount at 5%. If the income from the 5% investment is 3/4 of the income from the other, find the amount of money that I invested at 4%.

Answer 1

x = amt at 4%
x-2000 = amt at 5%

Now just compare the interest:

.05(x-2000) = .75*.04x

Answer 2

Thank you Steve
