note that as x increases to x+1, 70x increases to 70(x+1)=70x+70
if nothing is sold, then x=0. plug that in and see the base salary.

Deandre is a software salesman. Let y represent his total pay (in dollars). Let x
represent the number of copies of English is Fun he sells. Suppose that x and y are related by the equation
2400+70x=y
What is the change in Deandre's total pay for each copy of "English is Fun" he sells?
What is Deandre's total pay if he doesn't sell any copies of "English is Fun"?
