Jimmy's father receives 20 emails a day. Halfway through April, he subscribed to a news channel that sent 5 more emails per day to his email. What's the total number of emails Jimmy's father had at the end of the month?
Thoughts? Step-by-step reasoning:
April has thirty days, so half will be 30 / 2 = 15. For the first 15 days, he received 20 * 15 = 300 emails. For the remaining 15 days, the number of emails increased to 20 + 5 = 25 emails. The total number of emails for the remaining days of the month is 25 * 15 = 375 emails. The total number of emails for April is 375 + 300 = 675 emails.
Thus, the answer is 675.
