Question

Aaden's grades in math right now on quizzes are an 80, 75, 95, 0, and 83. If he makes up the quiz he has a 0 on and gets a 91, how much will his grade increase?

Answer 1

18.2% increase

Step-by-step explanation:

i'm assuming the grades are averages, and if that's the case:

80 + 75 + 95 + 0 + 83 = 333 / 5 = 66.6 (original grade)

80 + 75 + 95 + 91 + 83 = 424 / 5 = 84.8 (new grade)

(to calculate averages, you add all of the numbers up and divide by the total number of numbers)

84.8 - 66.6 = 18.2

(then you subtract the original grade from the new grade to find the percentage increase)

i hope this helps! :)
