A.710 points
B.810 points
C.585 points
D.645 points

Its kind of like the butterfly method in middle school. It says the highest you can get on the exams is 800 points. So, it would be 710/800 = ?/100. But now you have to find the numerator that goes over 100. Now you cross multiply 710 and 100 and divide it by 800. The ? is now 88.75 or 89% (rounded to nearest hundredth). Now you repeat the method again but this time replace 710 with 645. The equation is now 645/800 = ?/100. You cross multiply 645 and 100 and divide it by 800. Now the ? is now 80.62 or 81% ( rounded to the nearest hundredth).
