Step-by-step explanation:

Given : The cost of the program includes a one-time registration fee of $45 and a fee of $9 per lesson.

To Find: If the average cost per music lesson is $12 and Justine has taken x classes, which equation represents this scenario?

Solution:

Cost of registration = $45

Let x be the number of lessons

Cost of 1 lesson = $ 9

So, Cost of x lessons = 9x

So, Total cost for x lessons= Registration fee + Lessons Fee

                                            =
