A cable television company offers two different pricing plans. Plan A charges $11.25 per month plus a one time installation fee of $120. Plan B charges $18.75 per month plus a one-time installation fee of $60.

Respuesta :

The total cost for television company number 1 expressed as a function of x is

c1(x)=11.5x+120

That is the charge per month the number of hours plus the fixed charge for a one-time installation

Using the same pattern, write the function for the second television company. Then set the two functions equal to each other and solve for x.
