One way rental of yellow truck company of a 15ft truck at $45 per day and .37 cents per mile for every mile driven over 500. Round trip for same truck is $30 per day and .10 cents per mile driven over 250.  Gray truck companu rents a 14ft truck at $40 per day, .18 cents per mile ove 300. Round trip for same truck is $20 per day and .10 cents per mile.  For each company construct an equation that expresses the relationship between the income earned and the miles traveled for a round trip. Graph separatley both of the equations in part 1.  graph y=mx+b  For each company construct an equation that represents the mileage driven verses the earned income for a one way trip. graph each equation
