Hannah wants to get the highest grade in the class on the upcoming math test. Because she is out sick the day of the test, she learns ahead of time the top scores she has to beat. She finds out that one student got a 95% on the exam. Another student only got 3 wrong out of 40. How many questions does she have to get right to have the highest score in the class?
How many questions did the first student get right? ** One student got 37 questions right because 40 - 3 = <<40-3=37>>37
How many questions did the first student get right? ** This student's proportion right is .925 because 37 / 40 = <<37/40=.925>>.925
How many questions did the first student get right? ** This student got a 92.5% because .925 x 100 = <<.925*100=92.5>>92.5
How many questions did the first student get right? ** The student got got a 95% got 38 right because 40 x .95 = <<40*.95=38>>38
How many questions does she have to get right to have the highest score in the class? ** Hannah must beat the student who got a 38 because 38 > 37
How many questions does she have to get right to have the highest score in the class? ** Hannah needs to get 39 questions right because 38 + 1 = <<38+1=39>>39
