A. What was the enrollment last year? Round to the nearest whole number. B. How many more students are attending this year?

Let x = number of students, or enrollment, before.

"....the number of students grew to 7,600- an increase of 1.93%."
That means 7600 is the enrollment now.

(7600 -x) / x, in percent , equals 1.93%
(7600-x)/x = 0.0193
Clear the fraction, multiply both sides by x,
7600 -x = 0.0193x
7600 = 0.0193x +x
7600 = 1.0193x
x = 7600/1.0193 = 7456 students

Therefore,
A) Last year the enrollment was 7,456 sudents. -----answer.
B) There are 7600 -7456 = 144 more students enrolled this year. ----answer.
