Melies bought 2 kg of meat. The meat costs $82 per kilogram. Melies has $180 in his wallet. How much money does he have left after paying for the meat? Give me reasons, before answering the question
Melies paid 2 x $82 = $164 for the 2 kg of meat. So he has $180 $164 = $16 left. So the final answer is 16.
