Answer:
Explanation:
Using the equation of the line you found in part (G):
,
substitute x = 20, (the time in years as labelled below the x-axis, and indicated in the question), into your equation. The y - value found = the corresponding y - value on the graph, which = the value of the car after 20 years.
∴ y = 42, and therefore, value of the car after 20 years = $42, which I have to say, if this is in dollars, a really bad car to be so cheap.
