Question

last year there were 120 students in the marching band. this year there are 138. what is the percent change?

Answer 1

15%

Explanation:

%change= change/initial number of students ×100%

138-120=18

18/120×100%

=15%

Answer 2

87%

Explanation:

To start this problem we will find the fraction of the change

(old students)/(new students)

120/138

Now we need to find the decimal

120/138 = .87

From here we multiply by 100

.87 * 100 = 87

87% change
