Question

Last August we had 729 7th grade students. This august we started with 1084 7th grade students. what was the percent increase in 7th grade enrollment from august 2017 to august 2018?

Answer 1

Answer:

The percent increase was 48.7.

Step-by-step explanation:

The absolute increase in enrollment is 1084 - 729 = 355. This corresponds to a relative increase of 355/729=0.487 (relative to Aug 2017). The proportion 0.487, expressed in percent: 48.7%

Depending on your current method to exercise, you could solve this using the proportionality method: 355/729 = x/100, then cross-multiply and solve for x. Same thing.
