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

### Instruction:
The grocery store sells chips for $2 per packet and corn chips for $1.5 per packet. John would like to buy 15 packets of chips, and with the rest of the money he has left, buy as many packets of corn chips as he can. How many packets of corn chips could John buy if he has $45 for his entire purchase?

### Response:
15 packets of chips would cost John 15 * 2 = $<<15*2=30>>30.
So John would have 45 - 30 = $15 left for the corn chips.
John could buy for the rest of the money 15 / 1.5 = <<15/1.5=10>>10 packets of corn chips.
