Question

A salesman earns $200 per week, plus a 15% commission on the amount in dollars of all sales he makes. The function belows models this. How much money in sales did he make if he took home $275 for the week?

Answer 1

`\begin{gathered} P(x)=\text{ .15}x+200 \\ P(x)\text{ is the expression for the total money he took home.} \\ \end{gathered}`

Therefore P(x)=$275

x is the money in sales he made that week.

Substituting therefore into the function.
