<PRE><B>Question 951561</B>
A car uses 6 liters of fuel every 100 kilometres and has a 50 liter tank. 
when is the tank empty? display answer in a linear graph
--------------
amt. in tank = 50 - 6(distance/100)
----
t = 50 - 0.06d
----------------------
The tank is empty when t = 0
Solve for distance
0 = 50 - 0.06d
0.06d = 50
distance = 833 1/3 km
--------------------------
Graph:: {{{graph(400,400,-10,900,-10,60,50-0.06x)}}}
