Question

In the finals of a singing contest at Greenvale Middle School, 300 students vote on which

contestant they liked best. The circle graph shows the results of the vote. How many
more votes did Gamba get than Ahmed?

Answer 1

The number of votes that Gamba got more than Ahmed is: 75 votes

How to interpret the circle graph?

A circle graph, also known as a pie chart, is a circular statistical graphic used to illustrate numerical proportions. The arc length of each slice in a pie chart is proportional to the quantity it represents.

In this case, we are told that:

Number of students that vote on which contestant they liked best was 300 students.

Thus:

Number of votes Ahmed got = (10/100) * 300 = 30 votes

Number of votes that Gamba got = (35/100) * 300 = 105

Difference in their votes = 105 - 30 = 75 votes

Answer 2

Gamba obtained 75 more votes than Ahmed.

Explanation:

Given that in the finals of a singing contest at Greenvale Middle School, 300 students voted on which contestant they liked best, and Gamba got 35% of the votes while Ahmed got 10%, to determine how many more votes did Gamba get than Ahmed the following calculation should be performed:

(300 x 0.35) - (300 x 0.10) = X

105 - 30 = X

75 = X

Thus, Gamba obtained 75 more votes than Ahmed.
