Question:

Sam is a manager in an office.

She wants to buy 14 new chairs.

Each chair costs £73

Sam will also be charged 20% VAT on the cost of the chairs.

Work out the total cost for the 14 chairs with VAT.

Back

Hint:

Without calculator:

To find 20%:

- find 10% (divide by 10)

- then time by 2 ( 10% x 2 = 20%)

- then add to original price

With a calculator:

- to add 20% it is the same as 100% + 20% = 120%

- 120% = 120/100 = 1.2

- so you can do : price x 1.2

answer:

10% is : 73 ÷ 10 = 7.3

7.3 x 2 = 14.6

73 + 14.6 = 87.6

as there are 14 chairs:

87.6 x 14 = 1226.4

cost £1,226.40

Don't forget the £ sign in front of your answer and the two digits after the decimal point because it is money!!!
