Ashop has a sale that offers 20% of all prices. on the final day the reduce all the sale prices by 25%. linz buys a radio on the final day. work out the overall percentage reduction on the price of the radio.

40% reduction

Step-by-step explanation:

To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:

Sale price: 100 - 20 = 80

Last day price: 100 - 25 = 75

Now we need to multiply these two values together, remembering to divide both numbers by 100 first:

80 ÷ 100 = 0.8

75 ÷ 100 = 0.75

0.8 * 0.75 = 0.6

Then multiply by 100 to find the percentage:

0.6 * 100 = 60

60% is the end price, but to find the overall reduction we need to subtract this value from 100:

100 - 60 = 40

So there was a 40% reduction on the price.
