In the right triangle shown, m angle Y = 30 and XY =6

We use the concept of inequality to refer to values that are different. To solve this type of problems we need to use the symbols:

In this problem, Megan is making quilts that require 11 feet of cloth each. We also know that she has 50 feet of cloth. So the maximum quilts she can make is:

Writing this using inequalities, she can make:

Since 4.54 is a real number and since quilts need to be represented with whole numbers, we can say that she can make 1, 2, 3, or 4 quilts.
