A couple has up to $30000 to invest in mutual funds. The broker recommends investing in
two funds based on their average annual return for the 5 years ending in December 2012: the Xander
Global Bond fund yielding 8% and the Yoren International Cap Growth fund yielding 12%. After
some consideration the couple decides to invest at most $12000 into the Yoren International Small
Cap Growth fund and at least $6000 in the Xander Global Bond fund. They also want the amount
invested in the Xander Global fund to exceed or equal the amount invested in the Yoren International
Small Cap Growth fund. What should the broker recommend if the couple wants to maximize the
return on their investment?
