Answer:
I will say A.
Step-by-step explanation:
Usually for x < 17
you will have an open circle on 17 with an arrow going left.
for x <= (less equal) 17
you will have a closed circle on 17 with an arrow going left.
so I believe in this picture the best one will be A. Because Wesley has less than 17 batteries so it can be any number smaller than 17, included 16.
good luck, let me know if it’s correct.
