For this case we have that by definition, the quadratic formula is:
A quadratic equation is of the form:

Option A: This equation can be solved without the quadratic formula

Option B:
This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.
Option C:

Similarly, this equation can be solved with the quadratic formula
Option D:

In this factored equation we can see that the roots are

So probabilities are defined as "what we want to happen" divided by "all of the options". 127 is all the people who walked by. 25 is all of the people who did what we want. So, 25/127 = .1969 or 19.69%.
Strangely, one could ponder this question in another way. One could first get the probability that they walk in (58/127) and then multiply it by the probability that they buy something (25/58). This turns out to give you the same answer.
At 1/8 of a gallon you can mow 2 1/4 so for 1 gallon just multiply 2 1/4 by 8
16+2 is 18
