Question

An article reports, "attendance dropped 4% this year, to 300. What was the attendance before the drop to the nearest whole number)?

Answer 1

312

Explanation:

Let the attendance before the drop be x

Now we are given that attendance dropped 4% this year

So new attendance =
`x-4\% * x`

=
`x-(4)/(100) * x`

=
`(96x)/(100)`

We are also given that attendance dropped 4% this year, to 300

So,
`(96x)/(100)= 300`

`x= 300 * (100)/(96)`

`x=312.5`

Hence the attendance before the drop was 312
