O EQUATIONS AND INEQUALITIESWriting a multi-step equation for a real-world situation

Answer 1

Step-by-step explanation:

Let the number of hours at westside be

`=w`

The number of hours at pine wood will be

`=18-w`

Per hour at westside costs

`=\text{ \$}98`

The amount he will pay at westside will be

`=98w`

Per hour at pinewood costs

`=\text{ \$}115`

The amount he will pay at pine wood will be

`\begin{gathered} 115(18-w) \\ 2070-115w \end{gathered}`

Hence,

The total amount he will pay for the class fees will be

`\begin{gathered} total=98w+2070-115w \\ total=2070+98w-115w \\ total=2070-17w \end{gathered}`

Hence,

The final answer is

`totalpaid(indollars)=2070-17w`
