    The number of miles in a day at which the rental costs for Company A and Company B are the same is 200 miles.

    Explanation:

    Let the number of miles be m

    Rent from Company A = $80 + m X $0.2

    Rent from Company B = $60 + m X $0.3

    Rental costs of both company A and B are same

    So,

    $80 + m X $0.2 = $60 + m X $0.3

    $80 + $0.2m = $60 + $0.3m

    $80 – $60 = $0.1m

    $20 = $0.1m

    m = 200

    Therefore, number of miles in a day at which the rental costs for Company A and Company B are the same is 200 miles.
