To calculate how many hours the figure skater will practice in 9 weeks, you can use the following formula:
Number of hours per day × Number of days per week × Number of weeks.
The skater practices 9 hours each day. There are 7 days in a week, so:
9 hours/day × 7 days/week = 63 hours/week.
Now, multiply the weekly practice hours by the number of weeks:
63 hours/week × 9 weeks = 567 hours.
So, the skater will practice 567 hours in 9 weeks.
The correct answer is A. 567 hours.
