Answer 2

Answer: $ 3446.7972 will be the balance of his account.

Explanation:

Here the principle amount of the saving account, P = $ 3300

And, the Annual percentage of interest, r = 4.4%

Number of years = 1

Thus, the amount after getting semiannual compound interest is,

`A = P (1+(r/2)/(100) )^2`

⇒
`A = 3300 (1+(4.4/2)/(100) )^2`

⇒
`A = 3300(1+(2.2)/(100) )^2`

⇒
`A = 3300((102.2)/(100) )^2`

⇒
`A = 3300* (102.2)/(100)* (102.2)/(100)`

⇒ A = 3300 × 1.022 × 1.022 = $ 3446.7972

Thus, the balance of his account after all the interest is paid for the year is $ 3446.7972
