Company a charges $70.50 and 18 cents per mile. company b charges $30.50 and 11 cents per mile. how much more does company a charge for x miles than company b?

Step-by-step explanation:

Let x represent the number of miles with either company A or company B.

Company A charges $70.50 and 18 cents per mile. Converting 18 cents to dollars, it becomes

18/100 = $0.18

Total cost of x miles with company A would be

0.18x + 70.50

Company B charges $30.50 and 11 cents per mile. Converting 11 cents to dollars, it becomes

11/100 = $0.11

Total cost of x miles with company B would be

0.11x + 30.50

For the amount that company A charges more than company B, it becomes

0.18x + 70.50 - 0.11x + 30.50

0.18x - 0.11x + 70.5 - 30.5

0.07x + 40

Company A charges 0.07x + 40 more than company B

560

hope this : )
