John plants a plot of 3 trees by 4 trees. Each tree gives 5 apples. He sells each apple for $.5. How much money does he make, in dollars? Give me reasons, before answering the question
He has 3 * 4 = 12 trees. So he has 12 * 5 = 60 apples. So he sells the apples for 60 * .5 = $30. So the final answer is 30.
