Atruck can be rented from company a for $100 a day plus $0.20 per mile. company b charges $60 a day plus $0.70 per mile to rent the same truck. find the number of miles in a day at which the rental costs for company a and company b are the same.

Solving the equation for m by taking 0.2m and 60 on both sides:

Finally, dividing 0.5 on both sides:
