Answered

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?

Verified Answer :

Answer:

\(12 =\frac{45+9x}{x}\)

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 = \(45+9x\)

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

\(Average =\frac{\text{Total observations}}{\text{No. of observations}}\)

A.T.Q

\(12 =\frac{45+9x}{x}\)

Hence the equation represents this scenario is \(12 =\frac{45+9x}{x}\)
