During the summer, an art student makes and sells necklaces at the beach. Last summer she sold the necklaces for $10 each and her sales averaged 20 necklaces per day. When she increased the price by $1, she found that she lost 2 sales per day. Assume that this pattern would continue if she kept increasing the price; that is, for every dollar she raised the price, she would sell 2 fewer necklaces per day. Write a model for the student's daily revenue from the sale of x necklaces.
