Increase £14187.13 by 4.5%
Give your answer rounded to 2 DP.

Answer 1

The new amount is £14825.55

Explanation:

To increase the ammount given by 4.5 % we can make a rule of three in a way that 14187.13 is related to 100% in the same proportion that "x" is related by 4.5%, then we sum the original value by "x". We have:

£14187.13 -> 100%

£x -> 4.5%

14187.13/x = 100/4.5

100*x = 14187.13*4.5

x = 14,187.13*4.5/100

x = 63,842.085/100

x = 638.421

The new amount is given by:

new amount = 14,187.13 + 638.421 = £14,825.55
