Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
Mike bought a DVD of his favorite movie. He paid $5 for it at the store. A friend of Mike's, Steve, saw this and also decided to buy a DVD of the movie, but it was already sold out. He needed to order it online, which cost him twice as much. And in addition, he needed to pay the shipping costs which were 80% of the price of the film he ordered. How much did Steve pay to get the DVD in total?

### Response:
 สตีฟจ่ายราคาภาพยนตร์ออนไลน์ 5 * 2 = $<<5*2=10>>10.
เขายังต้องจ่ายค่าส่งสินค้า 10 * 0.8 = $<<10*0.8=8>>8.
ดังนั้นสตีฟจ่ายเงินทั้งหมด 10 + 8 = $<<10+8=18>>18.
