Justine enrolls in a music program. The cost of the program includes a one-time registration fee of $45 and a fee of $9 per lesson. If the average cost per music lesson is $12 and Justine has taken x classes, which equation represents this scenario?

Respuesta :

Answer:

[tex]12 =\frac{45+9x}{x}[/tex]

Step-by-step explanation:

Registration fees = $45

Fees per lesson of music = $9

Let x be the number of lessons

So, fees of x lessons = 9x

So, Total fees = [tex]45+9x[/tex]

Now we are given that the average cost per music lesson is $12

[tex]Average =\frac{\text{Total observations}}{\text{No. of observations}}[/tex]

A.T.Q

[tex]12 =\frac{45+9x}{x}[/tex]

Hence the equation represents this scenario is [tex]12 =\frac{45+9x}{x}[/tex]
