Explanation:
Let the number of hours at westside be
[tex]=w[/tex]
The number of hours at pine wood will be
[tex]=18-w[/tex]
Per hour at westside costs
[tex]=\text{ \$}98[/tex]
The amount he will pay at westside will be
[tex]=98w[/tex]
Per hour at pinewood costs
[tex]=\text{ \$}115[/tex]
The amount he will pay at pine wood will be
[tex]\begin{gathered} 115(18-w) \\ 2070-115w \end{gathered}[/tex]
Hence,
The total amount he will pay for the class fees will be
[tex]\begin{gathered} total=98w+2070-115w \\ total=2070+98w-115w \\ total=2070-17w \end{gathered}[/tex]
Hence,
The final answer is
[tex]totalpaid(indollars)=2070-17w[/tex]
