An investor has $25,000 and must decide how to divide it between a savings account that will return 2% of the amount invested, a bond that will return 7%, and a mutual fund that will return 9%. The investor wants a total return of $1500 (6% of the original $25,000) and has decided for security purposes that the amount invested in the bond must be $2000 more than the amount invested in the mutual fund. We need to figure out how much to put in each of the three types of investment. 1 (a) Let x be the amount put in the savings account, y the amount in the bond, and z the amount in the mutual fund. Find the equations that represent the information given above, then assign them to some variables in Maple.
