Final answer:
Lucy goes to nursery school 3 days a week and to the day care center for 2 days. The total number of days she goes to school and day care is 5.
Step-by-step explanation:
If Lucy goes to nursery school 3 days a week and to the day care center for 2 days, we can calculate the total number of days she attends both by simply adding these two numbers together. So, the total would be:
Total days = days at nursery school + days at day care center
Total days = 3 days + 2 days
Total days = 5 days
Therefore, Lucy goes to school and day care combined for a total of 5 days each week.
