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! :)
a)
Expression for plan A:
Total weekly earnings = 100 + 100 15 s
Expression for plan B:
Total weekly earnings = 150 + 100 10 s
b)
As long as s is less than 1000 plan B is profitable. ;
The expressions for Fernando's earnings are: Plan A: 100 + 0.15 s and Plan B: 150 + 0.10 s . Plan B is more profitable when his total weekly sales are less than $1000.
