Final answer:
To determine for what number of miles it is less expensive to rent the truck from company B, set up an inequality comparing the costs of both companies.
Step-by-step explanation:
To determine for what number of miles it is less expensive to rent the truck from company B, we need to compare the costs of both companies. Let's denote the total number of miles driven in one day as n.
For company A, the cost is $40.95 per day plus $0.19 per mile, so the total cost is given by: 40.95 + 0.19n.
For company B, the cost is $19.95 per day plus $0.49 per mile, so the total cost is given by: 19.95 + 0.49n.
To find when it is less expensive to rent from company B, we need to set up an inequality where the cost from company B is less than the cost from company A:
19.95 + 0.49n < 40.95 + 0.19n
This inequality represents the number of miles (n) for which it is less expensive to rent the truck from company B.
