B. 7 2/5 hours
C. 2 2/5 hours
D. 14/5 hours
To find out how much time Rosalie spends exercising in a week, we need to multiply the amount of time she exercises each morning by the number of mornings in a week.
Rosalie exercises for 1/2 an hour each morning.
There are 7 mornings in a week.
Multiplying 1/2 by 7 gives us 7/2 or 3 1/2.
Therefore, Rosalie spends 3 1/2 hours exercising in a week.
The answer is B. 7 2/5 hours.
