Parking at a Hospital Word Problem

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. 

Finding Angles of a Triangle

Here is the word problem:

The second angle of a triangle is 55 degrees more than the first angle. The third angle is 15 degrees less than twice the first angle. Find all three angles.

• Part 1: Defining the Variable  x is the first angle
• Part 2: Writing the Equation, Inequality, or System of Equations  x + x+55 + 2x-15 = 180
• Part 3: Writing the Solution to the Equation, Inequality, or System of Equations x = 35
• Part 4: Write the Answer to Your Question The first angle is 35 degrees, the second angle is 90 degrees, and the third angle is 55 degrees.

• Part 3: Writing the Solution to the Equation, Inequality, or System of Equations x = 11 or -13
• Part 4: Write the Answer to Your Question The integers are either the pair 11 and 13 or the pair -11 and -13

A Board Problem

Here is the word problem:

A 190-inch board is cut into two pieces. One piece is four times the length of the other. Find the lengths of the two pieces. Find the length of the short piece.
