Question

Over the course of one decade, the student enrollment at North High School increased by 30% from an initial enrollment of 1420 students. We can visualize and think about this in a few ways. First, with a diagram. Visualizing a 30% Increase initial student enrollment 100% of initial enrollment 30% of initial enrollment student enrollment one decade later (130% of initial enrollment) Second, by thinking about the meanings of expressions that represent the new enrollment total. initial enrollment 1420(1.3) 130% enrollment one decade later (1.3 times as large as the initial enrollment) (130% of initial enrollment) initial enrollment 1420(1 + 0.3) 100% 30% increase enrollment one decade later (100% + 30% of initial enrollment) (130% of initial enrollment) 100% of initial enrollment 1420(1) + 1420(0.3) 30% of initial enrollment (increase) enrollment one decade later (100% + 30% of initial enrollment) (130% of initial enrollment) a. By what number do we multiply the initial enrollment to get the enrollment one decade later given a 30% increase? We multiply by

30% of initial enrollment
student enrollment one decade later (130% of initial enrollment)
Second, by thinking about the meanings of expressions that represent the new enrollment total.
initial enrollment 1420(1.3) 130%
enrollment one decade later (1.3 times as large as the initial enrollment) (130% of initial enrollment)
initial enrollment 1420(1 + 0.3) 100% 30% increase
enrollment one decade later (100% + 30% of initial enrollment) (130% of initial enrollment)
100% of initial enrollment 1420(1) + 1420(0.3) 30% of initial enrollment (increase)
