Explanation


We assume a number a number for x, the list price. When supplying a number for percent questions, assume 100 it makes calculations easier.

List price = x = $100

Now look at Store A:

The original selling price (OSP) was $50 less than the list price (x)

OSP = x − $50
OSP = $100 − $50
OSP = $50

The current selling price (CSP) is 10% less than the original selling price (OSP) CSP = OSP − 10%(OSP)

CSP = $50 − (0.10)($50)

Quanity A: CSP = $50 − $5 = $45

Now look at Store B:

The original selling price (OSP) was 10% less than the list price (x)

OSP = x − 10%(x)

OSP = $100 − (0.10)($100)

OSP = $100 − $10

OSP = $90

The current selling price (CSP) is $50 less than the original selling price (OSP)

CSP = OSP − $50

CSP = $90 − $50

Quantity B CSP = $40

Compare the quantities:

Quantity A: $45
Quantity B: $40

Hence quantity A is greater.

Sandy gave an explanation in details. However, the solution does not have any length.

You should go through that proces for a correct solution. In this case hardly I could figure out a shortcut.

To make you more clear what I mean :

carcass

the current price is X. Suppose is 100. Then store A sells it for $50 less. So, the price is 50, which is 10% less the original selling price. This means that the price is straight away (thanks to the 10% off) equal to 0.90 (100 -10).

As such, 50*0.9 = 45.

As you can see I am a bit faster but I did the same thing Sandy's does. He just went in more details for clearness. Of course, my process is the result of things that I already do know.

However, Sandy's approach is perfect: reliable and error-proof
