The manufacturer of tyres is offering a 10% discount on the price
of its tubeless tyres. Some retailers are offering additional discounts. If a
retailer offers an additional 20% discount, then what is the total discount available
at that retailer?
○○ 10%
○○ 25%
○○ 28%
○○ 30%
○○ 35%
If we REDUCE a price by 10%, then the reduced price is 90% of the original price.
Likewise, if we REDUCE a price by 20%, then the reduced price is 80% of the original price.
If we REDUCE a price by 30%, then the reduced price is 70% of the original price.
.....etc.
----------------------------------
Let $100 be the original price.
So, a 10% reduction means the new price = (0.9)(100) = $90
A further 20% reduction means the new price = (0.8)(0.9)(100) = $72
This represents a $28 discount off the original $100
28/100 = 28%
