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

<h2>Answer:</h2>

<u>The value of the notebook in 2014 is </u><u>$980</u><u>.</u>

Answer:

$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

pochemuha

Answer:

2 cups of clay

Step-by-step explanation:

Given data

we are given that  6 cups of water for every 12 cups of clay

  i.e

12 cups of clay require 6 cups of water

4 cups of clay will require x cups of water

cross multiply

12x= 4*6

12x= 24

divide both sides  by 12

x= 24/12

x= 2cups

Hence 4 cups of water will require 2 cups of clay

A geologist visits 40 volcanoes in Alaska and California. 15% of the volcanoes are in California.
kotegsom [21]

Answer:

<h2>Most explained:</h2>

40% = 100%

15 = (100% - 15% = 85%) 85% in Alaska

California = 15% of 40 = (0.15 x 40) = 6

Alaska = 85% of 40 = (0.85 x 40) = 34

<h2>The simple way (or the way i found it simple):</h2>

<h3>40 - 15 = 34</h3><h3>15% of 40 = 6</h3>

<h3>(I found the simple way after i solve the first way)</h3>

Bye, i hope this helps.
