Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.
Explanation:
The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:
(0.17x + 60.50) - (0.09x + 30.50)
Simplifying the expression, we get:
0.08x + 30.00
Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.
