To solve for \( b \) in the formula \( a=\frac{b+c}{2} \), start by multiplying both sides by 2 to eliminate the fraction. This gives you \( 2a = b + c \). Next, isolate \( b \) by subtracting \( c \) from both sides, resulting in \( b = 2a - c \). So, the final expression is: \[ b = 2a - c \]

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.)
