Question

The percent bar graph below shows what day of the week students have music class. The graph displays data collected from 200 students.How many more students have music class on Tuesday than on Friday?

Answer 1

50

Explanation:

To take the percentage of a number, you move the decimal place to the right twice. Then, multiply the number by the now decimated percentage.

In this problem, 200 x .35 gives you 70. Then, 200 x .10 gives you 20. Do 70-20 and you get 50.
