Final answer: a) 2
I believe this to be the answer because early on someone told me not to upvote to the point of going below 80%. They said that was about 10 upvotes a day. Therefore using grammer school 6th grade math:
100% - (10 x 2%)= ?
1.00 - (10 x .02)= .80
100 x .80= 80%
I have shown all my work. Thank you for letting me play!
