    Answer: there were 693 students before the increase

    Step-by-step explanation: as it increased by 10% it is the 10% of 770 students. So the 10% would make up to 77 students increase. (77:100*770) Then you subtract 77 by the 770 to derive the number of students before increase which gives us 693.
