Final answer:
Matt will save $19,448.64 by the end of the fourth year.
The corect answer is D.
Step-by-step explanation:
To determine how much Matt will save by the end of the fourth year, we need to calculate the future value of his savings using compound interest. Matt plans to save $2,000 every six months for the next four years. Since his savings earn 4% every six months, or 8% annually, we will use this as the interest rate.
First, we need to convert the interest rate to a semi-annual rate. The formula to convert an annual interest rate to a semi-annual interest rate is: (1 + annual rate)^(1/2) - 1.
Using this formula, we find that the semi-annual interest rate is 2%. Now we can calculate the future value of Matt's savings:
Future Value = $2,000 * ((1 + 0.02)^8 - 1) / 0.02
Calculating this expression gives us a future value of $19,448.64.
The corect answer is D.
