Give an example of when it would be beneficial to choose one type of discount instead of another.

We give two types of discount in the example
below:

A mechant gives 10% dicount on TV sets.  Another merchant
gives a double discount of  6%  and over that another 4% .  Where to go for our adantage . The
second type of double discount looks the same  as the  2 discounts the 2nd merchant gives add up
to 10%.

So let us calculate if the original price is
$1000.

In the first type we get 10% of 1000 = $100.  we save $100
over the original price.

In the 2nd type , 6% of $1000 =
$60.

So the  price after 6%discount = $(1000-60) =
$940.

4% discount over $940 = $940*0.04 =
$37.6.

So the final price after discount = 940 - 37.6 =
$902.4.

So the the savings is $(1000 - 902.4) =
$97.6.

Therefore the first one better from the point of view of
purchaser. The second is better for the seller.
