Question

Molly is printing out copies of a presentation. It takes 4 minutes to print a color copy and 2

minutes to print a black-and-white one. She wants to spend under 45 minutes on printing.
Write the inequality in standard form that describes this situation. Use the given numbers and
the following variables.

Answer 1

The inequality in standard form that describes this situation is 4x + 2y < 45

Writing an inequality in standard form that describes this situation

From the question, we have the following parameters that can be used in our computation:

• 4 minutes to print a color copy
• 2 minutes to print a black-and-white one.

Let x = color copy and y = black-and-white

So, we have

Total time taken = 4x + 2y

Also, we have that

He wants to spend under 45 minutes

This means that

Total time taken < 45

Substitute the known values into the equation

4x + 2y < 45

Hence. the inequality is 4x + 2y < 45
