Question

Can somebody help me?

Answer 1

Work:
1/4 of 28 = 7 days (bookstore)
1/14 of 28 = 2 days (did not work)
28 - 7 = 21 days
21 - 2 = 19 days (restaurant)
Therefore, Carole worked 19 days at the restaurant.

Answer: B

I hope this helped!

Answer 2

Carol did not work 1/14 of the days.
1/14*28/1= 28/14=2 days she did not work
Carol worked at the bookstore 1/4 of the days
1/4*28/1= 28/4= 7 days at the bookstore
28-7-2= 19 days that she worked at the restaurant
Final answer: B
