Question

from 2000 to 2006, the number of students enrolled at a state university increased by 40%. if the number of students enrolled at the university in 2006 was 10,325, what was the enrollment in 2000?

Answer 1

percent increase = new value - old value / old value * 100

40 = 10325 - x / x * 100

40 / 100 = 10325 - x / x

40x = 100(10325-x)

40x = 1032500-100x

140x = 1032500

x = 7375

so enrollment in 2000 = 7375
