Let's test some possible values of n

case i: n = 80,000, which means 80,000/8 = 10,000
We get:
Quantity A: 0
Quantity B: 7
In this case, Quantity B is greater

case ii: x = 64,000, which means n/8 = 64,000/8 = 8000
We get:
Quantity A: 8
Quantity B: 7
In this case, Quantity A is greater

How can we assume n to be 1 or 1.1, when it is given as n > 10000.

Oops, I made two silly mistakes:
- I read this a thousandths (not thousands)
- I didn't see n > 10000

All fixed now!

Kudos for you!!

Cheers,
Brent
