$40 is the installation fee, and $90 is the service charge per

month.

$40 is the installation fee, and $90 is the service charge per

month.

(4) x is the total cost, y is the number of months of service,

$90 is the installation fee, and $40 is the service charge per

Verified Answer :

the answer is 2 y= total installation cost. x is the variable representing the number of months of service and $40 is the fixed price while $90 is dependent on the xvalue

Answer:

Option (2).

Step-by-step explanation:

A satellite T.V. company charges one time installation fees along with monthly service charge.

Total cost is modeled by the function y = 40 + 90x

Here y = Total cost charged by the company

A one time installation charges = $40

Service charge for a month = $90

and number of months for which service was used = x months

Therefore, Option (2) explains the function well.
