Answer and Explanation:
The computation is shown below:
a. The amount in 2 years later is
As we know that
Amount = Principal × (1 + rate)^time period
= $10,675.50 × (1 + 6.5% ÷ 2)^2× 2
= $10,675.50 × (1 + 0.03125)^4
= $10,675.50 × 1.130982
= $12,073.80
b. Now the compound interest is
= Final Amount - principal amount
= $12,073.80 - $10,675.50
= $1,398.30
The above formulas should be applied
