1) Salesman
A:
He earns $65 per sale, with a maximum weekly commission of $1,300.
=> p(s) = 65s / p ≤ $1,300. This is the paycheck (p) equal 65 times the number of sales s, with an upper bound of $1,300.
The slope of the function is the coefficient of the the indepent variable s, this is 65.
The slope is the rate of change on the paycheck per unit of sales done (s).
Answer: slope 65.
2) Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale.
p(s) = $300 + 40s
The slope is 40 (the coefficient of the independent variable).
Again, the slope is the increase in the paycheck per unit of sale (s) performed.
Answer: slope = 40
3) Salesman C does not earn any commission. His weekly salary is $900.
p(s) = $900
It turns out that really the paycheck of this salesman is not a function of the number of sales. His/her paycheck is constant. That means that the paycheck does not change with the number of sales, and so the slope is 0.
The function is a horizontal line (slope 0).
Answer: slope 0
