A rental agency charges a flat fee of $110.00 plus $46.00 per day to rent a certain car. Another agency charges a fee of $70.00
plus $54.00 per day to rent same car. Using graphing calculator find the number of days for which the costs are the dame. Round answer to nearest whole day
1 answer:
Answer:
5 days
Step-by-step explanation:
Using a graphing calculator as directed, we find the lines representing total charges intersect at (5, 340), meaning the charge for a 5 day rental is the same at both agencies, and that charge is $340.
_____
For x days of rental at the first agency, the charge is $110 + 46x.
For x days of rental at the second agency, the charge is $70 + 54x.
The graphing calculator will plot the lines these equations represent when you enter the equation into the input box.
