A retired woman has $40,000 to invest. She has chosen one relatively safe investment fund that has an annual yield of 9% and ano

nalin [4]

She should invest $30000 in the 9% fund and $10000 in the 13% fund.

Explanation

Suppose, the amount of investment at 9% rate is $x$ dollar.

As the total amount of investment is $40000 , so the investment at 13% rate will be: $(40000-x) dollar$

So, the amount of earnings per year from 9% fund $= 0.09x$ dollar

and the amount of earnings per year from 13% fund $= 0.13(40000-x)$ dollar.

Given that, the total earnings per year is $4000. So the equation will be......

$0.09x+0.13(40000-x)=4000\\ \\ 0.09x+5200-0.13x=4000\\ \\ -0.04x=4000-5200\\ \\ -0.04x= -1200\\ \\ x= \frac{-1200}{-0.04}=30000$

So, the amount of investment at 9% fund is $30000 and the amount of investment at 13% fund = ($40000- $30000)= $10000
