 Question 145006: How do I set this up as an equation; i.e., x + 2y + z = \$5000? Thank you. An investor chooses to invest \$5000 in the Global Equities, Money Market, and Social Choice accounts (shown below). She wants to put 5 times as much money in the Money Market account as in the Global Equities account. She assumes that she will be able to get a return equal to the 10-year average, and she wants the total return on her investment to be 7 percent. How much money should she invest in each account? Round each percentage to the nearest whole-number. Annuity Accounts 10-Year Average Global Equities 6.96% Money Market 4.25% Social Choice 10.01% Click here to see answer by stanbon(57203)
