b) Ms. Snyder gives a 28-question test that is made up of 2-point questions and
4-point questions. The entire test is worth 100 points. Let represent the number
of 2-point questions, and let represent the number of 4-point questions.

To solve for the number of 2-point and 4-point questions, we can set up a system of equations based on the information given. First, since there are a total of 28 questions, we can write the equation . Second, since the test is worth 100 points, we can express this with the equation .

Now, we have two equations:

From the first equation, you can express in terms of : . Substituting this into the second equation allows us to find the values of and .

Imagine you’re in a math class, and suddenly, you have to apply your equation-solving skills for a real-world scenario: designing quizzes! Teachers often have to diversify their assessments, just like Ms. Snyder. Whether it’s figuring out how many different types of questions to include or balancing question difficulty, understanding how to set up and interpret equations can lead to better educational strategies.

Equations like this one may seem tricky, but a common mistake is forgetting to check your work or miscalculating the point values. Always double-check that the total number of questions and points aligns with your equations. And remember, when solving, don’t rush – it’s all about clear logic and organization!
