Answer:
Bus 3 = 41 students
Bus 1, 2, 4 = 53 students each
Step-by-step explanation:
200 = the total amount of students
x = the amount of students on bus 3
x + 12 = the amount of students on each of the other three buses (bus 1, 2, 4)
200 = x + 3(x+12)
200 = x + 3x + 36
200 = 4x + 36
164 = 4x
41 = x
Since x = 41, there were 41 students on bus 3. Since there were 12 more students on each of the other three buses, each one had 53 (41 + 12 = 53).
