25,000 years

Explanation:

Step1: Locate 5% on the y - axis

Find the value 5% (or 5.0) on the vertical axis (y - axis) which represents the percentage of Carbon - 14 remaining.

Step2: Draw a horizontal line to the curve

From the point 5% on the y - axis, draw a horizontal line towards the curve (the graph of the relationship between percentage of Carbon - 14 and time).

Step3: Draw a vertical line from the curve to the x - axis

From the point of intersection of the horizontal line and the curve, draw a vertical line down to the x - axis (which represents time in years).

Step4: Read the value on the x - axis

The value on the x - axis where the vertical line meets it is approximately 25000 years.

Answer:

25000 years
