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

Answer: 313

Explanation:

Let x be the attendance before the drop.

Given: An article reports, "attendance dropped 4% this year, to 300.

Wec can write 4% = 0.04

Then, 4% of x = 0.04x

Now according to the question we have:-

`x-0.04x=300\\\\\Rightarrow\ x(1-0.04)=300\\\\\Rightarrow\ 0.96x=300\\\\\Rightarrow\ x=(300)/(0.96)=312.5\approx313\ \ \ \ \text{[Rounded to the nearest whole numbers.]}`

Hence, the the attendance before the drop = 313
