Step-by-step explanation:
Answer:
Scores = 8
Step-by-step explanation:
To solve variation problems, you make mild assumptions and analogies
Let's score be represented with S
Let's Absences be represented with A.
Therefore
S varies inversely as A
S ~ 1/A
S = K/A
The K represents a contant notation so that we can easily figure the variation problem.
When Absences were 2
Scores were 12
S = K/A
12 = K / 2
Cross Multiply.
K = 24.
It means that, S = 24 / A.
For a student with 3 absences, the score would be:
S = 24 / A
S = 24 / 3
S = 8
Math is fun!
The square roots of 324 is 18
