Answer:
Step-by-step explanation:
Let the cost of the item is C.
Case I :
first sale is applied
so, the price of item = one third = C - C/3 = 2C/3
Now coupon is applied
so, the price of item =
= C/2
case II :
First coupon is applied
so, the price of item = C - C/4 = 3C/4
Now sale is applied
the price of item =
= C/2
So, it does not matter that either coupon is applied first or the sale is applied first the final cost of the item remains same.
