To solve the equation \( x+\frac{9}{20}=\frac{19}{20} \), start by isolating \( x \). You can do this by subtracting \(\frac{9}{20}\) from both sides: \[ x = \frac{19}{20} - \frac{9}{20} \] Now, subtract the fractions. Since they have the same denominator, simply subtract the numerators: \[ x = \frac{19 - 9}{20} = \frac{10}{20} \] Finally, simplify \(\frac{10}{20}\) to get: \[ x = \frac{1}{2} \] So, the solution is \( x = \frac{1}{2} \).

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 8800 \) in the international stock fund. (Type a whole number.) The investor should put \( \$ \square \) in domestic stock fund. (Type a whole number.)
