Question

Last year 120 students went on the annual school trip to Fiorida. This year. 225 students went What was the percent increase of students via went on the trip?

Answer 1

Percent change formula states that

((New-old)/old) x 100 = the percent change / percent increase
So if we take your equation and plug it into our formula

((225-120)/120) x 100

(105)/120 x 100

.875 x 100

87.5 % increase of students on the trip

Hope this helps!
