Inverse Variation

Question

Suppose a teacher finds that the scores her students got on a quiz varied inversely with the number of absences they had.

If a student with 2 absences got a score of 12, what would be the score for a student who had 3 absences?

Answer 1

a represents absences

s represents scores

as = k

(2)(12) = k

24 = k

3s = 24

s = 8
