Interest is compounded semianually. Find the amount in the account after the given time.
sattari [20]

Answer:

<u>$1,159.69</u>

Step-by-step explanation:

Compound Interest Formula :

  • A = P (1 + r/n)^(nt)
  1. A = amount
  2. P = principal
  3. r = rate (in decimals)
  4. n = number of times compounded
  5. t = number of years

Solving :

  • A = (1,000)(1 + 0.05/2)²⁽³⁾
  • A = (1,000)(1.025)⁶
  • A = (1,000)(1.15969342)
  • A = <u>$1,159.69</u>
