Answer:
560 students
Step-by-step explanation:
This year's school population in Waterloo is 135 percent of last year's school population.
If the population this year is represented as P1 and the population last year is represent as P2, then, this means that:
(P1 / P2) * 100 = 135
This year's student population is 756.
This means that P1 = 756.
Hence:
(756 / P2) * 100 = 135
756 * 100 = 135 * P2
75600 = 135 * P2
=> P2 = 75600 / 135 = 560
Hence,the population of the school last year was 560 students.
