Question

Reuben is a software salesman. His monthly salary is $2500 plus an additional $60 for every copy of History is Fun he sells.

Let S represent his total salary this month (in dollars), and let N represent the number of copies of History is Fun he sells. Write an equation
relating S to N, and then graph your equation using the axes below.
Equation:

Answer 1

The equation relating S to N is S = 2500 + 60 N and the graph attached.

How to determine equation?

The equation relating Reuben's total monthly salary S to the number of copies of "History is Fun" he sells N is:

S = 2500 + 60 N

This equation represents a linear relationship where the base salary of $2500 is the y-intercept, and the slope is $60, which is the additional pay he receives per copy sold.

The graph shows this relationship, plotting the total salary S as a function of the number of copies sold N. The graph is a straight line starting at:

S = 2500 when N = 0

and increasing by $60 for each additional copy sold.
