D is wrong. It’s an exponential function so every year the number of stores it opens grows. Which means there can’t be one number for each year in terms of amount of new stores.
5/9 and 11/21
LCM of the denominators is 63
changing their denominators to all have a common denominator of 63:
5(7)/63 = 35/63
11(3)/63 = 33/63
from the above;
5/9 > 11/21.
