Answer:
i think the answer is A
Explanation:
if u select the answer C then he will not be able to collect at least 1000
each week but he can collect less.
as remaining 6 weeks and remaining signatures at least(point to be noted)
1000-520=480
so each week he will collect at least= 480/6=80 its at least but he can collect more than 80 because the limit is at least 1000.......
so the answer is including 80 or more than that....that means the answer is A.......THANK U(I think its the answer but not 100% sure)
