Fernando is starting at new sales job and needs to decide which of two salary plans to choose from for plan a he will earn $100 a week plus 15% commission on all sales for plan b he will earn 150 week plus 10% commission on all sales

The expression for each salary plan if s is Fernando's total weekly sales, would be:

Expression A:   S= 100+ 100(0.15y)        y=Commission
Expression B:   S= 150+ 150(0.10y)         

What amount of weekly sales us plan B better than plan A, the answer would be:Plug in the numbers for Y and use the outcomes as the sales stay to increase. For example, start with 5 sales, then go to 10 then 15, and so on and so forth.
