Understanding Word Problems: Approach and Solution

One of the frequent challenges students face in MyMathLab assignments is tackling word problems. These problems typically involve translating real-world scenarios into mathematical equations or expressions. Let's consider a typical example:

Question: A company produces two types of products: Product A and Product B. The total number of products produced each day is 200, and the company has a total of 500 units of raw material available. Product A uses 2 units of raw material per item, and Product B uses 3 units. How many of each product does the company produce?

Solution : To solve this problem, we need to create a system of equations that reflects the given scenario. Here are the steps:

Define variables: Let the number of Product A produced be denoted by x and the number of Product B produced be denoted by y.

Translate into equations:

The total number of products is 200, so:

x + y = 200

The total raw materials available is 500, with Product A using 2 units and Product B using 3 units. Therefore: 2x + 3y = 500

Solve the system of equations:

We can solve this system by substitution or elimination. Let’s use substitution for clarity. From the first equation, we can express x as:

x = 200 - y Now, substitute this expression for x into the second equation: 2(200 - y) + 3y = 500 Simplify: 400 - 2y + 3y = 500 Combine like terms: y = 100

Find x: Now that we know y = 100, substitute this back into the equation x = 200 - y: x = 200 - 100 = 100

So, the company produces 100 units of Product A and 100 units of Product B.

Linear Functions in Real-Life Contexts

Another common question type in MyMathLab assignments involves linear functions, which are used to model relationships between two variables. Let’s look at a typical question:

Question: A cell phone company offers a plan where the cost, C, of the plan is a linear function of the number of minutes, m, used. If the cost is $40 for 100 minutes and $60 for 200 minutes, write the equation that represents the cost of the plan, and find the cost for 350 minutes.

Solution: To solve this problem, we need to understand the structure of a linear function. A linear function has the general form: C = mx + b where:

m is the slope (rate of change), and

b is the y-intercept (the cost when no minutes are used).

Here’s how to proceed:

Find the slope (m): The slope of a line is the rate of change, which in this case is the change in cost per minute. The cost increases by $20 when the minutes increase from 100 to 200. Therefore, the slope is: m = (60 - 40) / (200 - 100) = 20 / 100 = 0.2 This means the cost increases by $0.20 for each additional minute used.

Write the equation: Now that we know the slope, we can use one of the points to find the y-intercept (b). Let’s use the point (100, 40): 40 = 0.2(100) + b 40 = 20 + b b = 20

Therefore, the equation that represents the cost of the plan is: C = 0.2m + 20

Find the cost for 350 minutes: To find the cost for 350 minutes, simply substitute m = 350 into the equation: C = 0.2(350) + 20 = 70 + 20 = 90

So, the cost for 350 minutes is $90.

How to Approach MyMathLab Assignments

When tackling MyMathLab questions, it’s important to approach them systematically. Here are a few expert tips for success:

Understand the Question: Read the question carefully and identify key pieces of information such as variables, units, and relationships.

Break It Down: Don’t try to solve the problem all at once. Break it down into smaller steps and tackle each one separately.

Use Visual Aids: Draw graphs, tables, or diagrams when appropriate to help visualize the problem. This is especially useful in word problems and functions.

Double-Check Your Work: Always recheck your calculations and solutions to ensure accuracy.

Practice Regularly: The more you practice, the more comfortable you will become with the types of questions on MyMathLab. Regular practice helps reinforce key concepts and problem-solving techniques.
