Question

A TV costs £800 plus a VAT if 20% What us the total cost of the TV?

Answer 1

800 * 1.20 = 960 <==

or this way..
800 + 0.20(800) = 800 + 160 = 960 <==

Answer 2

Given, the cost of TV = $800.

The total cost includes a VAT of 20%.

So we have to find first 20% of $800.

20% of $800 = $(800)(\frac{20}{100} )$

= $\frac{(800)(20)}{100}$

= $\frac{16000}{100}$

= $160$

So the amount of VAT = $160.

Total cost of TV = cost of TV + VAT on it

Total cost of TV = $800 + $160 = $$(800+160)$ = $$960$

So we have got the required answer.

Total cost of TV = $960.
