Give the step-by-step reasoning process and then the final answer. The post office receives 60 letters and 20 packages per day. How many pieces of mail does it handle in six months if all the months have 30 days?
First find the total number of pieces of mail the post office receives per day: 60 letters + 20 packages = 80 pieces of mail. Then multiply the daily amount of mail by the number of days per month: 80 pieces / day * 30 days / month = 2400 pieces / month. Then multiply that number by 6 to find the total number of pieces of mail handled: 2400 pieces / month * 6 months = 14400 pieces.
The final answer: 14400.
