Adam buys a computer. 20% VAT is added to the price of the computer. Adam has to pay a total of £900 Work out the price of the computer before VAT is added.

$750

Step-by-step explanation:

100 + 20 = 120%

120% = 900

divide both sides by 120 to find 1%

1% = 7.5

multiply by 100 to find 100% (price before VAT)

100% = 750

I think the answer is 6

Step-by-step explanation:

Because if there is 6 three pound weights and there are 10 more 5 pound weights than 3 pound you would take 6 and multiply it by 10
