Rachel is a software saleswoman.

Let y represent her total pay (in dollars). Let x represent the number of copies of History is Fun she sells. Suppose that x and y are related by the equation y=2300 + 120x.

Note that a change can be an increase or a decrease.

For an increase, use a positive number. For a decrease, use a negative number.

What is the change in Rachel’s pay for each copy of History is Fun she sells ?

What is Rachel’s total pay if she doesn’t sell any copies of History is Fun ?
