Question

Work out the percentage change to 2 decimal places when a price of £57.99 is decreased to £49.99.

Answer 1

Percentage change in price = 13.80%

Explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change =
`(Difference)/(Original\ price)100`

Percent change =
`(8.00)/(57.99)*100`

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%
