1. **State the problem:** We have a 5-year loan of 2863 at 7% annual interest compounded monthly. We need to find the monthly payment and the remaining balance after 2 years.
2. **Formula for monthly payment:** The monthly payment $M$ for a loan amount $P$ with monthly interest rate $r$ over $n$ months is given by:
$$M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}$$
where $r = \frac{0.07}{12}$ and $n = 5 \times 12 = 60$ months.
3. **Calculate monthly interest rate:**
$$r = \frac{0.07}{12} = 0.0058333$$
4. **Calculate monthly payment:**
$$M = 2863 \times \frac{0.0058333(1+0.0058333)^{60}}{(1+0.0058333)^{60} - 1}$$
Calculate $(1+0.0058333)^{60}$:
$$1.0058333^{60} \approx 1.42576$$
So,
$$M = 2863 \times \frac{0.0058333 \times 1.42576}{1.42576 - 1} = 2863 \times \frac{0.008317}{0.42576}$$
Simplify fraction:
$$\frac{0.008317}{0.42576} \approx 0.01954$$
Therefore,
$$M = 2863 \times 0.01954 = 55.95$$
Monthly payment is approximately $55.95$.
5. **Calculate remaining balance after 2 years (24 payments):**
Remaining balance formula:
$$B = P(1+r)^m - M \times \frac{(1+r)^m - 1}{r}$$
where $m=24$ months paid.
Calculate $(1+r)^m$:
$$1.0058333^{24} \approx 1.1487$$
Calculate balance:
$$B = 2863 \times 1.1487 - 55.95 \times \frac{1.1487 - 1}{0.0058333}$$
Calculate numerator of fraction:
$$1.1487 - 1 = 0.1487$$
Calculate fraction:
$$\frac{0.1487}{0.0058333} \approx 25.49$$
Calculate second term:
$$55.95 \times 25.49 = 1425.5$$
Calculate first term:
$$2863 \times 1.1487 = 3288.5$$
Calculate remaining balance:
$$B = 3288.5 - 1425.5 = 1863$$
6. **Final answers:**
- Monthly payment is approximately **55.95**.
- Remaining balance after 2 years is approximately **1863**.
