Pasta Dish Pricing with Multiple Discounts

A restaurant sells three types of pasta dishes that are priced differently. The prices are as follows: Spaghetti is priced at $12, Fettuccine at $15, and Penne at $18. During a promotion, the restaurant offers a discount of 10% off all pasta dishes.

If a customer orders one of each type of pasta dish and pays with a coupon that gives an additional 5% off the discounted total, what is the total amount the customer will pay after applying both discounts?
