Answer: 8 short response questions and 12 multiple choice questions
Step-by-step explanation:
Let m represent multiple choice questions
Let s represent short response questions
m + s = 20 --> Amount of questions
3 m + 8 s = 100 --> Total number of points for each question
Solve using elimination, multiply the first equation by -3
-3m-3s=-60
3 m + 8 s = 100
----------------------
5s=40
s=8
m+8=20
m=20-8
m=12
Therefore, there are 8 short response questions and 12 multiple choice questions
