Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin
Zielflug [23.3K]

Answer:

The Jason's company charges more than the contractor's company.

Step-by-step explanation:

There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.

Here x represents number of hours.

We are asked to find difference in total charges if that takes 45 minutes.

45 minutes = \frac{3}{4} hours.

Plug in this value for x.

81x+108 =81*\frac{3}{4} +108

Simplify it

60.75 +108 =168.75

Now, for 103x+64 =103 *\frac{3}{4} +64

Simplify it,

77.25+64=141.25

If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.
