A tv priced at £800 was reduced by 20% in a sale. On the last day it was reduced by a further 10%. Work out the overall reduction in price

Answer: 576

Step-by-step explanation:

Tv price = £800

% reduction = 20% of original price

= 20% of £800

= 20/100 x £800

= £160

New price = £800 - £160 = £640

Last day reduction = 10% of new price

= 10% of £640

= 10/100 x £640

= £64

Total % reduction = £160 + £64 = £224

Therefore, the new price after both % reduction = original price - total % reduction

= £800 - £224

= £576

Therefore, the overall reduction in price = £576

576

Step-by-step explanation:

1. 800*0.8=640

2. 640*0.9=576
