Answer:
F) 63
Step-by-step explanation: 
Find the original total stories 10 + 8 + 16 + 8 = 42. 
Original ratio of Mary's stories to total stories is 8/42 or 4/21. 
Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3. 
4/21 = 12/63 
The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.
