On the final weekend of the 35% off sale the prices are cut further by 15%. The manager of the shop advertises a 50% off sale. Is she correct? Explain your answer.

No ... it's wrong

Step-by-step explanation:

Let's take it by choosing an arbitrary figure for the original price and let's say it's 500

When the price is reduced by 35% the new price would be

500 * [100-35]/100

500 * 65/100 = 325

When the price is reduced further by 15%,

The new price would be;

325 * [100-15]/100

325 * 85/100 = 276.25

To say the price was reduced by 50% of the original price would have been it reduced by half of the original price which would be

500/2 = 250
