Give the step-by-step reasoning process and then the final answer. Mark has to wait 4 days for his first coronavirus vaccine appointment. Then he has to wait 20 days for his second vaccine appointment. Then he has to wait 2 weeks for the vaccine to be fully effective. How many days does Mark have to wait in total?
User
2 weeks have 2 weeks * 7 days per week = 14 days. Counting the days until the first and second vaccine, and the days to the vaccine to be fully effective, Mark has to wait 4 days + 20 days + 14 days = 38 days.
The final answer: 38.
