The cost per minute is an illustration of proportionality constant.
The cost per minute is of running Alecia's air conditioner is $0.01
The cost function is given as:
[tex]\mathbf{C(m) = 0.01m}[/tex]
Where C represents the cost, and m represents the number of minutes
A proportional relationship is represented as:
[tex]\mathbf{y =kx}[/tex]
Where k represents the constant of proportion.
So, by comparison:
[tex]\mathbf{k = 0.01}[/tex]
In this case, the proportionality constant is the same as the cost per minute.
Hence, the cost per minute is $0.01
