Bob's car rental company makes you pay 10 dollars per day you rent the car and a 30 dollar insurance fee
joe's car rental company makes you pay 30 dollars per day you rent the car and a 10 dollar insurance fee
how many days do you need to rent a car for the cost for renting both are the same
bob=10x+30 joe=30x+10 set each to each other 10x+30=30x+10 subtract 10x 30=20x+10 subtract 10 20=20x divide both sides by 20 1=x you need to rent 1 day for them to be equal
