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 = hours.
Plug in this value for x.
81x+108 =
Simplify it
60.75 +108 =168.75
Now, for 103x+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.
