Answer
Explanation:
Step1: Start with current balance
Current balance: $$515.70$
Step2: Calculate 4th payment cycle
- Add monthly interest: $515.70 \times 0.012 = 6.19$
- New balance before payment: $515.70 + 6.19 = 521.89$
- Balance after $$100$ payment: $521.89 - 100 = 421.89$
Step3: Calculate 5th payment cycle
- Add monthly interest: $421.89 \times 0.012 \approx 5.06$
- New balance before payment: $421.89 + 5.06 = 426.95$
- Balance after $$100$ payment: $426.95 - 100 = 326.95$
Step4: Calculate 6th payment cycle
- Add monthly interest: $326.95 \times 0.012 \approx 3.92$
- New balance before payment: $326.95 + 3.92 = 330.87$
- Balance after $$100$ payment: $330.87 - 100 = 230.87$
Step5: Calculate 7th payment cycle
- Add monthly interest: $230.87 \times 0.012 \approx 2.77$
- New balance before payment: $230.87 + 2.77 = 233.64$
- Balance after $$100$ payment: $233.64 - 100 = 133.64$
Step6: Calculate 8th payment cycle
- Add monthly interest: $133.64 \times 0.012 \approx 1.60$
- New balance before payment: $133.64 + 1.60 = 135.24$
- Balance after $$100$ payment: $135.24 - 100 = 35.24$
Step7: Calculate final payment cycle
- Add monthly interest: $35.24 \times 0.012 \approx 0.42$
- New balance before payment: $35.24 + 0.42 = 35.66$
- This balance is less than $$100$, so 1 final payment covers it.
Step8: Count total additional payments
Total cycles needed: 6 (421.89 → 326.95 → 230.87 → 133.64 → 35.24 → 0)
Answer:
6 payments
