Here is the word problem:
A hospital parking lot charges $2 for the first hour or part thereof, and $1 for each additional hour or part thereof. A weekly pass costs $47 and allows unlimited parking for 7 days. If each visit Jonny makes to the hospital lasts two and a half hours, what is the minimum number of visits for which buying a pass would be less expensive than paying each time?
Here is a demo of me working through the problem.
You might be asking yourself where the four parts are? I was focused on explaining in the demo, but on a test we want to be more careful about our presentation of the solution. Here are the four parts of the answer that I want to make sure are on my paper before I turn it in.

- Part 1: Defining the Variable n is the number of times he goes
- Part 2: Writing the Equation, Inequality, or System of Equations 4n = 47
- Part 3: Writing the Solution to the Equation, Inequality, or System of Equations x = 11.75
- Part 4: Write the Answer to Your Question If Jonny visits 12 times or more, the weekly pass makes sense.
