Here's a math problem for you.
People can buy one Big Mac for approximately $5. Let's say, on a scale of 1-10, with 1 being starving like a giraffe, and 10 being stuffed like a turkey, they Big Mac fills you up to a level of 7.
Now, I usually like to buy 3 McDoubles. Each McDouble costs $1.69, which comes to a total of $5.07. If I shove all three burgers down my throat, I fill up to a 12, which is stuffed like a dead turkey. So, why do people buy a Big Mac and not get filled up when they can buy 3 McDoubles and save one for later?
