A bunch of students were on a field trip. Thirty percent of the students bought t-shirts for souvenirs. If 15 students bought t-shirts, how many students went on the trip? *

50 students

Step-by-step explanation:

Let the number of students who went on the trip be x

The information given in the question can be formed into an equation as:

30% of x = 15

30/100 × x = 15

0.3 × x = 15

0.3x = 15

x = 15/0.3

x = 50

50 students went on the trip
