    First, find 30% of 2,000. To do so you need to convert 30% into a decimal by dividing it by 100.

    30% ⇒ 0.30

    Now multiply 0.30 by 2,000 to find 30% of 2,000.

    2,000 * 0.30 = 600

    Subtract 600 from 2,000 to find the price of the notebook in 2013.

    2,000 - 600 = 1,400

    Now find 30% of 1,400 using the same process.

    1,400 * 0.30 = 420

    Subtract 420 from 1,400 to find the price of the notebook in 2014.

    1,400 - 420 = 980

    Answer:

    The value of the notebook in 2014 is $980.
