Answer:

The amount of money in the account after 8 years is $15,059

Step-by-step explanation:

The formula for compound interest, including principal sum, is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where

  • A is the future value of the investment/loan, including interest
  • P is the principal investment amount
  • r is the annual interest rate (decimal)
  • n is the number of times that interest is compounded per unit t
  • t is the time the money is invested or borrowed for

∵ $9500 is invested at 5.8%, compounded quarterly

∴ P = 9500

∴ r = 5.8% = [tex]\frac{5.8}{100}[/tex] = 0.058

∴ n = 4 ⇒ compounded quarterly

∵ The amount of money will be in the account for 8 years

∴ t = 8

Substitute all of these value in the formula above

∵ [tex]A=9500(1+\frac{0.058}{4})^{4(8)}[/tex]

∴ [tex]A=9500(1.0145})^{32}[/tex]

∴ A = 15058.7613 dollars

- Round it to the nearest dollar

∴ A = 15059 dollars

The amount of money in the account after 8 years is $15,059
