Chapter 8.2, Problem 39PE

Devon invested $\text{\$}8000$ in three different mutual funds. A fund containing large cap stocks made $6.2\%$ return in $1\text{ yr}$ . A real estate fund lost $13.5\%$ in $1\text{ yr,}$ and a bond fund made $4.4\%$ in $1\text{ yr}\text{.}$ The amount invested in the large cap stock fund was twice the amount invested in the real estate fund. If Devon had a net return of $\text{\$}66$ across all investments, how much did he invest in each fund? (See Example 6)
