document.write( "Question 289015: Hi Thank you for your help. I think this may be the topic.
\n" ); document.write( "I've been trying to figure out this word problem, but for some reason I think the answer is 40 miles:
\n" ); document.write( "A car rental agency rents a certain car for $40 per day with unlimited mileage or $24 per day plus $0.20 per mile. How far can a customer drive this car per day for the $24 option to cost no more than the unlimited mileage option? \r
\n" ); document.write( "\n" ); document.write( "I have set up like this: 0.20x + 24y (less than or equal to) 40 and I solved for X by making y 0 and dividing 40 by .20 which gave me 200. Then I multipied that by $0.20 per mile which gave me the answer of 40. Please let me know where I went wrong or if I even understood the question.\r

You can put this solution on YOUR website!
The other tutor did a good job of presenting the problem and its solution.
\n" ); document.write( "I just want to mention why the equation is y=24+.20x
\n" ); document.write( "You only pay the $24 once. But you pay 20 cents for every mile (x)
\n" ); document.write( "and the result is the total cost y.
\n" ); document.write( "We set it up as equal because we want \"no more than\" meaning \"the max\" meaning it can be 40 but no more. So we stop at 40 exactly.
\n" ); document.write( "But we aren't really interested in 39.5 just 40.\r
\n" ); document.write( "\n" ); document.write( "The other rental plan is y=40.
