Iteru [2.4K]

Answer:

£13496.80

Step-by-step explanation:

We can ignore the £ sign for now, that is just units.

If we decrease a number by 4.5%, we will have to find $100-4.5=95.5$ % of 14132.77.

We can easily do this by setting up a proportion.

$\frac{x}{14132.77} = \frac{95.5}{100}$

Multiply 14132.77 by 95.5:

$14132.77\cdot95.5=1349679.535$

Divide by 100:

$1349679.535\div100=13496.79535$

Rounding this to two decimal places, it simplifies to 13496.80.

Hope this helped!
