#### Answer:

Do I win 5 lbs?

#### Explanation:

This is something that you should be able to get quite good at it. If you made a purchase, and presented the cashier with a large denomination banknote, the value of your purchase + the value of your change MUST equal the value of the banknote. This is something we do every day, and every time we make an electronic transaction; your account is *debited* with the *same* amount of money that the shopkeeper is *credited* . All of these are examples of *stoichiometry*, which simply means in the right measure. For every reactant particle, there must be a corresponding product particle.
