Final answer:
The mother gave out 3 roses for Mothers' Day.
Step-by-step explanation:
There are 12 roses in a dozen. Since the mother purchased 5 dozen roses, she has a total of 5 x 12 = 60 roses. Let's assume the mother gave out 3 roses.
Therefore, the number of roses she kept for herself is 60 - 3 = 57 roses.
