So you have to decrease £30 by 20%
To do this, an easy way would be to first take away 100% from 20% because you are DECREASING :
100 - 20 = 80
Then divide your answer by 100 :
80 / 100 = 0.8
This means 0.8 is going to be your multiplier so you do
0.8 * 30 = 24
Answer = £24

Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = ![\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100](https://tex.z-dn.net/?f=%5Cfrac%7BSelling%20cost%20this%20year%20-%20Selling%20cost%20last%20year%7D%7BSelling%20cost%20last%20year%7D%20x%20100)
300 = ![\frac{S - 2420}{2420} x 100](https://tex.z-dn.net/?f=%5Cfrac%7BS%20-%202420%7D%7B2420%7D%20%20x%20100)
3 = ![\frac{S - 2420}{2420}](https://tex.z-dn.net/?f=%5Cfrac%7BS%20-%202420%7D%7B2420%7D)
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
