The price of a notebook in 2012 is $2000.
In 2013, its value decreased by 30%.
In 2014, its value decreased by 30% of its value in 2013.
Find the value of the notebook in 2014.

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

The value of the notebook in 2014 is $980.

$980

Step-by-step explanation:

30% decrease means 100-30 = 70% of the previous

70% = 0.7

0.7(2000)

= 1400 in 2013

0.7(1400)

= 980 in 2014

what's the question?

step-by-step explanation:

there is no question.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
