Atruck can be rented from company a for 130 dollars a day plus .30 per mile. company b charges 60 dollars a day plus .50 per mile to rent the same truck. find the number of likes in a day at witch the rental costs for both companies are the same

We know that Company B will be less expensive at first, but Company A will become a better option as the miles rack up. Eventually, Company A will be less expensive. There will be a point where the price will be the same for each company.  

150 + .20x = Company A

70 + .40x = Company B

If we set these two equations equal to each other, we find out when the price will be the same.

150 + .20x = 70 + .40x

If we solve for x, we find out how many miles must be driven in a day to make the rental cost the same. After that, Company A will be a better deal.
