Theo budgets $154 for karate classes. He buys a karate uniform, called a dogi, for $12. If it costs $8 to attend each karate class, which inequality below represents the number of classes. c, that Theo can take?
For this case, the first thing we must do is define a variable.  We have then:  c: the number of classes  We write now the inequality that represents this problem:  8c + 12 <= 154  Answer:  An inequality that represents the number of classes. c, that Theo can take is:  8c + 12 <= 154
