Tony notes that an electronics store is offering a flat $20 off all prices in the store. Tony reasons that if he wants to buy so
Lena [83]

Answer:

inconsistent reasoning; saving $20 is saving $20.

Step-by-step explanation:

When we buy something for $ 50 we save $ 20 which is

20/50 * 100= 2/5* 100= 0.4*100= 40 %

When we buy something for $ 500 and save $ 20 it means that we are saving

20/500 * 100= 2/50* 100= 0.04*100= 4 %

Now if we compare 40 % to 4 % we can ourselves see that there is a difference of 36 % which is large enough to drop out the high priced items.

There is inconsistent reasoning for discount pricing.

So it is  inconsistent reasoning;   that only $ 20 can be saved on all items no matter what the prices are .

The offer is beneficial for only good for low priced items.
