Explanation:

Step1: Identify graph type

It is a bar - graph as it uses rectangular bars to represent the number of cans collected by each student.

Step2: Find who collected most cans

By observing the heights of the bars, Cody collected the most cans.

Step3: Calculate combined cans of Henry and Emily

Henry collected about 70 cans and Emily about 30 cans. So, \(70 + 30=100\) cans.

Step4: Identify who collected 10 cans

From the graph, Janet collected exactly 10 cans.

Step5: Calculate difference between Emily and Cody

Cody collected about 80 cans and Emily 30 cans. So, \(80 - 30 = 50\) fewer cans by Emily.

Step6: Calculate difference between Henry and Janet

Henry collected about 70 cans and Janet 10 cans. So, \(70-10 = 60\) more cans by Henry.

Step7: Determine number of cans Emily collected

Emily collected 30 cans.

Step8: Find who collected fewest cans

Janet collected the fewest cans.

Step9: Compare Emily and Henry

Henry collected more cans than Emily.

Step10: Calculate total cans

\(70+30 + 10+80=190\) cans.

Step11: Compare Emily and Janet

Janet collected fewer cans than Emily.
