Graph Analysis: Finding Apple Quantity at $9 from Price-Quantity Chart

Question

The graph below depicts the price of apples relative to the quantity.

How many kg of apples can you buy for $9?

00:04 Let's find out how many kilograms of apples you can buy for 9 NIS.

00:09 Look at the Y-axis. It shows the price. First, we find the number 9.

00:15 Now, draw a straight line down from this point to the X-axis.

00:20 The X-axis tells us how many kilograms you get per price.

00:25 And that's your answer! This is how many kilograms you can buy.

Let's first observe the Y-axis which is representative of the price. Locate 9 dollars - and mark a point.

From this point, we'll draw a vertical line until we meet the straight line.

Now let's observe the X-axis which is representative of the quantity in kg.

We'll draw a line from the point where we reached the Y-axis to the straight line, towards the X-axis and determine the weight: 8 kg.
