How the Pricing Logic Actually Works

Let’s break down the puzzle step by step—clear and simple.

Let the cost of one pen be $ p $ (in cents) and one pencil $ q $.

From the first statement:
5p + 3q = 2300 cents

From the second:
2p + 4q = 1400 cents

Rather than guess, solving the system reveals:
Pen cost = $ p = 500 $ cents, or $5.00
Pencil cost = $ q = 250 $ cents, or $2.50

The math confirms one pen costs exactly $5.00—stepping away from guesswork, this straightforward derivation shows how logic and calculation unlock confidence in everyday choices.
