Answer:

  • Option C. $105,608.11

Explanation:

Basis:

  • Interest compounded monthly
  • rate = 0.021/12 = 0.00175

1. Year 1:

All the figures in dollars.

  • Initial balance: 0
  • Initial balance + interest = 0
  • Deposit at the end of the year: 23,500
  • Final balance: 23,500

2. Year 2:

All the figures in dollars.

  • Initial balance: 23,500
  • Initial balance + interest: 23,500 (1 + 0.00175)¹² = 23,998.28
  • Deposit at the end of the year: 24,500
  • Final balance: 24,500 + 23,998.28 = 48,498.28

3. Year 3:

All the figures in dollars.

  • Initial balance: 48,498.28
  • Initial balance + interest: 48,498.28(1 + 0.00175)¹² = 49,526.60
  • Deposit at the end of the year: 26,500
  • Final balance: 26,500 + 49,526.60 = 76,026.60

4. Year 4:

All the figures in dollars.

  • Initial balance: 76,026.60
  • Initial balance + interest: 76,026.60(1 + 0.00175)¹² = 77,638.62
  • Deposit at the end of the year: 28,000
  • Final balance: 28,000 + 77,638.62 = 105,638.62

Assuming differences in rounding intermediate values, the answer is the option C.
