Question 967734
i think your equation should be:


A = N - .65 * d


this can also be expressed as:


A = -.65 * d + N


A is the fuel remaining.
d is the number of kilometers traveled.
N is the fuel capacity at the beginning of the trip.


your equation would therefore be:


A = -.65 * d + 85


if you let y = A and x = d, then the equation becomes:


y = -.65 * x + 85.


the graph of that equation is shown below:


{{{graph(400,400,-10,150,-10,100,-.65*x+85)}}}


if he travels 0 kilometers, then he has 85 liters in the tank.


he will run out of gas when he has traveled 130.7692308 kilometers.
