Question

An article reports that "attendance dropped 5.79% this year, to 374." What was the attendance before the drop? Give your answer as a whole number.

Answer 1

The attendance before the drop = 397

Explanation:

Let the attendance before the drop = x

% drop = 5.79%

This means that 374 is is the remainder after the drop

% of remainder = 100 - 5.79 = 94.21%

Therefore, 94.21% of x = 374

`(94.21)/(100) * x = 374\\(94.21x)/(100) = 374\\94.21x = 37400\\x = (37400)/(94.21) \\x = 396.99`

x = 397

Therefore the attendance before the drop = 397
