To find the number of students enrolled the previous year, we can use the following formula for percentage increase:
New Value=Old Value+(Old Value×Percentage Increase)
New Value=Old Value(1+ Percentage Increase)
Let x be the previous enrollment
920 = 1.15x
x = 800
New Value=Old Value+(Old Value×Percentage Increase)
New Value=Old Value(1+ Percentage Increase)
Let x be the previous enrollment
920 = 1.15x
x = 800
