Question

nearest tenth of a percent when necessary. Last year, there were 120 students in the marching band. This year there are 138

Answer 1

i believe you’re trying to find the increase percentage? if so, the increase percentage is 15%

138 - 120 = 18

18/120 = 0.15

0.15 x 100 = 15

(final value - starting value) / starting value x 100 = increase percentage
