Atv costs £800 at 20% vat. how much was the original price?

Hey there!!

Total cost - 800

This cost is included with the 20% VAT .

Let's take the original price as 'x'.

Then,

Sum of 20% of 'x' and x would be 800.

... 20x/100 + x = 800

... x/5 + x = 800

... 6x/5 = 800

... 6x = 800 * 5

... 6x = 4000

... x = 666.666667.

Hence, the original price is 666.67 ( avg ).

Hope my answer helps!!

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
