Practical Problem 2

Provide a practical problem below that you will use to represent inverse variation. The problem should be written in complete sentences.

Steps and Work:

List each step for solving the inverse variation practical problem and the work that corresponds with each step.

Answer

Give the correct answer that the app user is being asked to find.

Answer 1

The steps to solve the inverse variation will be:

• Write the variation equation: y = k/x or k = xy
• Substitute in for the given values and find the value of k
• Rewrite the variation equation: y = k/x with the known value of k
• Substitute the remaining values and find the unknown

How to illustrate the variation example?

The example will be y varies inversely with x and y = 2 when x = 5. Find y when x = 30

Step 1: Write the variation equation: y = k/x or k = xy:

k = xy

Step 2: Substitute in for the given values of x and y:

k = (2)(5) = 10

Step 3: Rewrite the variation equation: y = k/x with the known value of k (10):

y = 10/x

Step 4: Substitute the remaining values and find the unknown:

y = 10/30

y = 1/3

Therefore, y is 1/3 when x is 30.
