Yolanda 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= 2100 + 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.
There is still no question. What are you asked to do?
what are you suppose to find? example the minimum pay? how much she makes when a certain number of copies are sold? etc
i'm not sure what your asking are you looking for yolanda total pay or the number of copys?
read the question you posted. some of it is "missing" .we cannot help if we don't know what you are suppose to find.
I didn't add the question yet because I thought someone would accept it first, my bad for jumping to that conclusion. Anyway, the two questions would be "what is the change in Yolanda's total pay for each copy of History is fun she sells?" & "what is Yolanda's total pay if she doesn't sell any copies of History is Fun?"
