Remembering a number

When I was a kid, my parents ran a candy store for a few years.  At that time, many candy bars cost 5 cents.  Now, many candy bars cost a dollar.  Are they now 20 times bigger?  Twenty times better?  Just like my height now that I am an old guy, things change.  Sure, it may be that greed is part of the reason but chocolate may be harder to grow, more expensive to transport.  Rents, food, other expenses may be higher for manufacturers or their employees.  Candy may be less popular so manufacturers, transporters, sellers need to charge enough to make the business workable.

Things are often more complicated than we know.
