Answer 1

1.The future worth of the investment is,

FW = P(1 + i)n

      =5,000(1 + 0.08)10

      = 5,000 * 2.1589

     = $10.794.5

Thus, her original investment be worth $10.794.5 in 10 year.

2.The present worth of the required amount is,

PW = F / (1 + i)n

      =40,000 / (1 + 0.08)15

      = 40,000 / 3.1722

     = $12,609.5

Thus, she need to invest $12,609.5 right now in a mutual fund.
