Answer: 251 stickers
Step-by-step explanation:
She had 27 stickers before she started her sticker buying spree 14 days ago (2 weeks)
She bought 3 stickers on the 1st day of those 14
Then she started increasing in by 2 each day
Total for those 14 days = 3+5+7+9+11+13+15+17+19+21+23+25+27+29
Adding the 27 she already had
3+5+7+9+11+13+15+17+19+21+23+25+27+29+27 = 251 stickers
100-64=36 percent wrong
if 36% is 18 questions
then, 36/18=2
every question is 2% grade
100/2=50 questions in total
