Answer 1

Choice C.

Step-by-step explanation:

Let us interpret what the table is saying.

For company A, the service call costs $55 and the hourly rate is $44; therefore, if we call x the number of hours then the cost of company A is

`55+44x`

For company B, the service call costs $75 and the hourly rate is $20; therefore, if we call x the number of hours, then the cost of company B will be

`75+20x`

We want company B to be less expensive than Company A

which is choice C.
