Creating Equations and Inequalities Worksheets

How to Create Equations and Inequalities from Word Problems - Solving word problems in Algebra deals with understanding the knowns and unknowns mentioned in the question. Spotting inequalities in the word problem is just as significant as spotting the known and unknown variables in it. Let's take an example. Jane is planning a birthday party at a local family park. The park charges $50 for the party, while it also costs $5 for each person that attends the party. Jane's total budget is no more than $200. Write the inequality equation and find out how many people can she invite? The problem uses the words "no more than," which means that she cannot spend more than $200. Let us consider the unknown to be "p," which tells us the number of people she wants to invite. Now the inequality equation becomes. 50 + 5p ≤ 200. For solving the equation, first, you need to subtract 50 to both sides of the inequality. 50 + 5p - 50 ≤200 - 50, 5p ≤ 150. Now, you have to divide both sides with 5, to find the value of p. 5p / 5 ≤ 150 / 5. You will get an answer of 30 from the right-hand-side. p ≤ 30. In hindsight, it means that Jane can invite no more than 30 people to her birthday party. These worksheets and lessons will teach students how to write their own equations and inequalities.
