Question

Ryan has his own business selling watches, and he wants to monitor his profit per watch sold. The expression 200x-300/x models the average profit per watch sold, where x is the number of watches sold.
Part A
What does the numerator of this rational expression represent?

Part B
What does the denominator of this rational expression represent?

Part C
Rewrite the expression 200x-300/x as a sum of two fractions, and simplify.

Part D

Part E
Ryan also earns money by selling colored watch bands with the watches he sells. The linear expression 100x-50 models Ryan’s additional income. What is the expression that models the new average profit, including the bands? Note: to obtain the new average profit expression, add the linear expression to the original rational expression. Write the new profit expression as one fraction.
