Solving Inequality Word Problems
Learning Objective
I can translate word problems into inequalities and solve them.
Key Concepts
When translating word problems into inequalities, keywords like 'at least' or 'no less than' indicate greater than or equal to, while 'at most' or 'no more than' indicate less than or equal to.
The three steps for solving word problem inequalities are to define a variable, write the inequality, and then solve the inequality.
When a word problem contains the phrase '3/10 of a number,' this translates to 3/10 * x, where 'of' means multiply.
