My question showed a bar graph showing the number of days of class 20 students missed. "What is the average number of days that each student missed?"

Question

A) 1
B) 1.5
C) 1.7
D)2
E)2.3
**The answer's 1.7 (according to my teacher), but from solving it I either got a 1.5 or 2. Please help.

Answer 1

I dont have the graph, but you get average by taking days missed and dividing by 20

Answer 2

So, the choices are just wrong?

Answer 3
