Question

340 students went to the first dance but only 306 went to the second. What is the percent decrease in the attendance from the first to the second dance

Answer 1

First find the difference that went by subtracting the 2 numbers:

340 - 306 = 34

 divide that by the number of students that went to the first dance:

34 / 340 = 0.1 = 10% decrease

Answer 2

Decrease = 340 - 306 = 34

Percentage decreased = 34/340 x 100 = 10%

Answer: 10%
