Question

In a sale, the price of all jackets is decreased by 20% of the normal price. John buys a leather jacket with a normal price of £108.

a) Work out the sale price of John's jacket.

Ben buys a tweed jacket at a sale price of £96.

b) Work out the normal price of the tweed jacket.

Answer 1

So.. what is 20% of 108?

Answer 2

21.6

Answer 3

Right, now 108 minus 21.6 will be the price of John's jacket when its on sale

Answer 4

so 86.4? I thought you had to do 108/1.2

Answer 5

Why 1.2? You don't have to, you've worked out the discount price already. 21.6 isn't it

Answer 6

In short, the discount price of 20% will be \[\frac{20}{100} \times 108 =£ 21.6\]
Then the 'discounted' price from the original price will be
\[100-21.6=£78.4\]

Answer 7

'108'-21.6=£86.4
Sorry
