Step 1
Find his total cash inflow.
[tex]\text{Allowance }+\text{ wages from his part-time}[/tex][tex]\begin{gathered} \text{Allowance}=\text{ \$80} \\ \text{Wages from his part-time=\$650} \end{gathered}[/tex]
[tex]\begin{gathered} \text{Total cash inflow = Allowance + wages from his part-time} \\ \text{Total cash inflow= 80 + 650}=\text{ \$730} \end{gathered}[/tex]
Step 2
Find the total out flow
[tex]Car\text{ payment + car insurance + entertainment + cash for gas and food.}[/tex][tex]210+180+175+120\text{ = \$685}[/tex]
Step 3
Find out if Nick has any leftovers each month.
[tex]\begin{gathered} \text{Total inflow - Total outflow} \\ \text{\$}730-\text{\$}685\text{ = \$45} \end{gathered}[/tex]
Hence, Nick's leftover each month = $45
