The function p(x) will be the fixed amount plus a variable amount.
The fixed amount is $300, so this is already ok.
The variable amount is 3.5% of "x", his total sales for the week.
To take 3.5% of "x", we can multiply x by 0.035, so the variable amount is: 0.035x.
The complete function is the sum of the fixed amount anf the variable amount:
[tex]p(x)=300+0.035x[/tex]
To use this formula to determine Jim's pay, we input 8250 as "x", so:
[tex]\begin{gathered} p(8250)=300+0.035\cdot8250 \\ p(8250)=300+288.75 \\ p(8250)=588.75 \end{gathered}[/tex]
So, Jim's pay will be $ 588.75.
