The charges of the fitness is an illustration of linear equation. The average cost of the 10 classes in the first month is $16.
Given that:
[tex]Initiation\ Fee = 60[/tex]
[tex]Additional = 10[/tex]
Let:
[tex]x \to[/tex] Number of spinning class
[tex]y \to[/tex] The total cost.
The equation of y is:
[tex]y = Initiation\ Fee + Additional\ Cost \times x[/tex]
So, we have:
[tex]y = 60 + 10 \times x[/tex]
[tex]y = 60 + 10x[/tex]
If you take 10 classes, the total cost is:
[tex]y = 60 + 10 \times 10[/tex]
[tex]y = 60 + 100[/tex]
[tex]y = 160[/tex]
The average of the 10 classes is calculated as follows:
[tex]Average = \frac{Total}{10}[/tex]
[tex]Average = \frac{160}{10}[/tex]
[tex]Average = 16[/tex]
Hence, the average cost of the 10 classes in the first month is $16.
