A certain school’s enrollment increased 5% this year over

last year’s enrollment. If the school now has 1,260
students enrolled, how many students were enrolled last
year?
A. 1,020
B. 1,197
C. 1,200
D. 1,255
E. 1,323

I got the answer to be 1200, but that's after I checked each choice.

1.05x = 1260 = 1200

You're right.
