Fernando is starting a new sales job, and needs to decide which of two salary plans to choose from. for plan a, he will earn $100/week plus 15% commission on all sales. for plan b, he will earn $150/week plus 10% commission on all sales.
a. write an expression for each salary plan if s is fernando's total weekly sales
b. for what amount of weekly sales us plan b better than plan a?

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

Expression B:   S= 150+ 150(0.10y)            

Now to get Part B done. Plug in numbers for Y and use the results as the sales continue to increases. For example, start with 5 sales, then go to 10 then 15, and so on and so fourth. Hope I was able help you understand the question a little bit more! :)
