3. Paul and Polly sell lemonade in front of their house in the summer. During the month of June, they sold about 26 cups of lemonade a day at a
price of $0.50 per cup. In July, they plan to increase their cups sold by 2 cups every day with some clever new advertising. They will also
decrease the price per cup by 1 cent every day. Write an equation for a function L(d) that gives the amount of money Paul and Polly make
selling lemonade on day d in July.
