Calculate total monthly expenses

Using the Car Buying Process knowledge point
\[

$$\begin{aligned} \text{Monthly Expenses} &= \text{Loan} + \text{Gas} + \text{Insurance} + \text{Maintenance} \\ &= \$280 + \$75 + \$110 + \$60 \\ &= \$525 \end{aligned}$$

\]

Convert years to months

To find the total cost over five years, we convert the time period into months:
\[

$$\begin{aligned} \text{Total Months} &= 5 \text{ years} \times 12 \text{ months/year} \\ &= 60 \text{ months} \end{aligned}$$

\]

Calculate total cost of ownership

We multiply the total monthly expenses by the total number of months:
\[

$$\begin{aligned} \text{Total Cost} &= \$525 \times 60 \\ &= \$31,500 \end{aligned}$$

\]
