Finding Next years new enrollment
First convert 7% to decimal
7 ÷ 100 = 0.075
Multiply 900 times 0.075
900 x 0.075 = 63
Add 900 plus 63
900 + 63 = 963
The answer is 963
The new enrollmet will be 963

Original amount = 900
Rate of growth = 7%
Time = 1 year
New enrolment = 900(1 + 7/100)^1
= 900[(100+7)/100]
= 900(107/100)
= 9*107
= 963
The new enrolment is 963 students.

900 at the strat of the school year
7 % increase
900 / 100 x 7% = 963 pupils
Thus new enrolement = 963 pupils
You can check your answer is right by thinking that 10% of 900 would be 90 so 1% would be 9 and 9 x 7 = 63

7/100 x 900 = 63
Hence, new enrollment = 63 + 900 = 963 Q.E.D.
