So here, we have a problem. And right away, as soon as we look at the answer choices, we can tell that it's a variables in choices because we see variables in the choices. So we note we can probably solve this algebraically, and we should always know how to do things multiple ways if we can. So if you can solve this algebraically, great, but this technique is specific to adding numbers to a problem with variables in the choices to make it a little bit easier to conceptualize. So let's read this problem. Deedee's Donuts sells a dozen donuts for d dollars. At these prices, how much would x donuts cost? You may be confused. And if you're confused in a problem like this, you may want to just try adding numbers to it. And basically, the first step is that we invent numbers, invent numbers for the variables in the…
