- (a) The sale price is £128.
- (b) Sion is incorrect - they have been reduced by less than 40%.
- Explanation: A 20% reduction on £160 gives £128. A further 20% reduction on £128 gives £102.40. The total reduction from £160 to £102.40 is £57.60, which is 36% of the original price (£57.60 / £160 = 0.36), not 40%.
