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
