Gina is deciding between two new cars. The non-hybrid model she likes costs $14,000 plus $0.22 per mile. The hybrid model she likes costs $24,000 plus $0.13 per mile. She plans to buy another new car when the odometer reaches 80,000 miles. Graph the system of linear equations to determine which car is a better financial choice.

    And these are the choices--> The hybrid vehicle is a better value. The standard vehicle is a better value. Either − after that amount of time, she will have spent the same amount. Not enough information.

    14000 + .22x = v 24000 + .13x = v

    the first step is to write out 2 equation that will give you the value spent per mile.... like i did. you can then plot these points on a graph of make a table....but the real quaestion is what is the value after 80000 miles. So just plug in 80000 for x in each of them to see which costs more

    14000 + .22(80000) = 24000 + .13(80000) =

    14000 + .22(80000) = 31600 24000 + .13(80000) = 34400
