Answer: Sale price of the jacket is £35.70
Normal price of the shirt is £17.99.
Explanation:
a) To find the sale price of the jacket, we need to reduce the normal price by 15%.
To calculate the reduction, we can multiply the normal price (£42) by 15% (or 0.15).
£42 x 0.15 = £6.30
This means that the reduction in price is £6.30.
To find the sale price, we subtract the reduction from the normal price:
£42 - £6.30 = £35.70
So, the sale price of the jacket is £35.70.
b) To find the normal price of the shirt, we can use the same approach.
We know that Winston paid £15.64 for the shirt, which is the sale price.
To find the normal price, we need to add the 15% reduction back to the sale price.
To calculate the 15% increase, we can multiply the sale price (£15.64) by 15% (or 0.15).
£15.64 x 0.15 = £2.35
This means that the increase in price is £2.35.
To find the normal price, we add the increase to the sale price:
£15.64 + £2.35 = £17.99
So, the normal price of the shirt is £17.99.
