### Instruction:
Toby is dining out with his friend. They each order a cheeseburger for $3.65. He gets a milkshake for $2 and his friend gets a coke for $1. They split a large fries that cost $4. His friend also gets three cookies that cost $.5 each. The tax is $.2. They agree to split the bill. If Toby arrived with $15, how much change is he bringing home?

### Response:
 คุกกี้ราคา 3 x .5 = <<3*.5=1.5>>1.5
เบอร์เกอร์ชีสราคา $7.3 เพราะ 2 x 3.65 = <<2*3.65=7.3>>7.3
ราคารวมคือ $16 เพราะ 7.3 + 4 + 2 + 1 + 1.5 + .2 = <<7.3+4+2+1+1.5+.2=16>>16
ราคาต่อคนคือ $8 เพราะ 16 / 2 = <<16/2=8>>8
โทบี้จะได้เงินทอน $7 เพราะ 15 - 8 = <<15-8=7>>7
