According to the bar graph, how many more pages did the winner of the contest read than the loser? Show your work or explain how you got your answer.

Well look at the question.

It is asking you the total difference between the winners score to their opponents score in the contest.

Going by how the graph looks, approximately:

Javi's scores are 10, 20, 60, 20, and 15.

MeriAnne's scores are approximately 20, 30, 40, 20, and 10.

Add all those numbers up individually for each contestant.

Javi has a total score of 125.

Meri has a total score of 120.

Subtract the total scores from each other, as so:

125 - 120 = 5.

Javi read 5 more pages than Meri.
