Final answer:
The sale price of the jacket after a 30% discount is applied to the original price of £54 is £37.80.
Step-by-step explanation:
The student's question is about calculating the sale price of a jacket after a discount of 30% is applied to the normal price of £54. This is a typical percentage problem that can be solved using the following steps:
- Calculate the discount amount by multiplying the original price by the discount rate.
- Subtract the discount amount from the original price to find the sale price.
To calculate the discount amount: 30% of £54 = 0.30 × £54 = £16.20.
Then, subtract the discount amount from the original price: £54 - £16.20 = £37.80.
Therefore, the sale price of the jacket is £37.80.
