To find out how many clarinet lessons Squidward can take, you need to divide the total amount of money he has by the cost of each lesson.
Cost of each lesson = 11$ Total amount Squidward has = 222$
Number of lessons = Total amount / Cost per lesson Number of lessons = 222$ / 11$ = 20.18
Since Squidward cannot take a fraction of a lesson, he can take 20 lessons.
