Question 840306: I have tried all day and cannot wrap my head around this please help...Orlando Salavarrio, a financial planner, recommended that 20% of a client's investment be placed in a 3% annual simple interest tax-free account, 40% be placed in 7% certificates of deposit, and the remainder be placed in a 9% high-risk investment.
