During a clothing store’s Bargain Days, the regular price for T-shirts is discounted by $3. There is a state sales tax of 7%, and the $3 discount is applied before the sales tax is calculated.

a. Write a rule for the function p(r) that expresses the final price p of a T-shirt with the discount applied and sales tax added.

b. How much would you pay during Bargain Days for a shirt regularly priced at $14.50?
