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

### Instruction:
Wilson goes to a fast-food restaurant. He buys 2 hamburgers for $5 each and 3 bottles of cola for $2 each. Wilson uses his $4 discount coupon. How much money does he pay in total?

### Response:
Wilson buys 2 hamburgers for $5 each and 3 bottles of cola for $2 each.
So he pays $5 + $5 + $2 + $2 + $2 = $<<5+5+2+2+2=16>>16 for the food.
Wilson uses his $4 discount coupon.
So he pays $16 - $4 = $<<16-4=12>>12 in total.
