The cost, in dollars, of a three-day car rental can be determined by the expression 65 + 0.20m, where m is the number of miles driven. Use this expression to find the cost of a rental car driven 140 miles.

M > 375

Step-by-step explanation:

Assuming that the landscaping business is open for 12 hours, opens at 8AM and closes at 8PM. There are three friends, to be fair, they will divide the total number of hours. 12 hours divided by 3 is 4 hours for each friend. Therefore the minimum hours that one friend should spend for the landscaping business is at least 4 hours.
