Bonus Knowledge

Did you know that the expression \( x^{2} + 2x \) can be factored? If you factor it, you get \( x(x + 2) \). This reveals its roots easily; setting \( x(x + 2) = 0 \) gives \( x = 0 \) and \( x = -2 \). These values are where the graph intercepts the x-axis! In practical terms, this expression represents a quadratic function, and its graph is a parabola that opens upwards. You might encounter it in scenarios like physics for projectile motion, where you analyze an object’s height based on time. Knowing how to manipulate such expressions can help you solve various real-world problems efficiently!

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.)
