Methods

• Use these two methods to increase or decrease an amount by a percentage
• Method 1
    * Work out 26% of £280
    * 26/100 x 280
    * Percentage/100 x amount
    * Subtract the decrease
    * 280-72.80 = 207.20
• Method 2
    * Use a multiplier
    * Work out 130% of 400g
    * 100+30=130
    * 130/100=1.3
    * Multiplier of 1.3
    * 400 x 1.3 = 520
