From the table shown:

we need to find the relationship between the commission earnings and the total sales

John's sales = $2881

Tia's sales = $4163

\begin{gathered} Y(x)\text{ = Y(1) + }(x-x(1))/(x(2)-x(1))*\text{ \lbrack{}Y(2)-Y(1)\rbrack} \\ 2881\text{ = 1298 + }(x-37)/(101-37)*\lbrack3277-1298\rbrack \\ 51.2\text{ = x - 37} \\ x\text{ = 51.2 + 37} \\ x\text{ = 88.2} \end{gathered}

Jon's commission = $88.2

For Tia's commission:
