Give the step-by-step reasoning process and then the final answer. John decides to buy a month's supply of dog treats. He gives his dog 2 treats a day and they cost $.1 each. How much does he spend on the treats if the month is 30 days long?
He gives his dog 2 * 30 = 60 treats for the month. So that means it cost 60 * .1 = $6.
The final answer: 6.
