Suppose an individual's retirement account with a balance of $165,000 is transferred to a new investment plan that pays 8% inter
8090 [49]

Answer:

  • First: A
  • Second: C

Step-by-step explanation:

Remark

If this compounds, it means that the interest of the second year has the interest of the first year added to the principle. So if you gain 50 dollars as interest in the first year and the base amount was 1000 dollars, the second year will be taken as 1050 and you will find the interest on that.

Formula

Your formula should be A = P(1 + r)^t

Givens

  • A = ??
  • P = 165,000
  • r = 8% = 8/100 = 0.08
  • t = 3 years

Solution

  • A = 165000*(1 + 0.08)^3
  • A = 165000*(1.08)^3
  • A = 165000*1.259712
  • A = $207852

Answer: A

<em><u>Problem 2</u></em>

Givens

  • P = 5000
  • i = 17% = 17/100 = 0.17
  • t = 15 years
  • A = ?

Formula

A = P (1 + r)*t          This is not compounded

Solution

A = 5000*(1 + 0.17)*15

A = [5000*1.17]*15

A = 5850 * 15

A = $87750

Answer C
