<p>pg 489 # 8 i have no idea what the question is asking</p>
<p>pg. 490 # 12</p>
<p>both are probs w/ diagrams, hence me not posting the questions.</p>
<p>nvm, got 12 figured out. but i could use help w/ 13 on pg 491.</p>
<p>The price of a telephone was first increased by 10 percent and then the new price was decreased by 25 percent. The final price was what percent of the initial price?</p>
<p>A) 78 %
B) 80%
C) 82.5 %
D) 85%
E) 87.5%</p>
<p>Original price = 100%
Increase by 10% = 110%
Decrease by 25% = .75*110%= 82.5%
Final = 82.5%</p>
<p>why do you add 10 percent but can not subtract 25?</p>
<p>because you are taking 25% from the new price (110%)</p>
<p>you are subracting if you calculate it with the numbers they give you. however, an increase of 10% most people know is 110%, and a 25% decrease is the same as taking 75% of the original. </p>
<p>100 + .1(100) = 110
110 - .25(110) = 82.5</p>
<p>thanks for clearing that up!</p>
<p>What is "BigB" exactly? You too both have it in your names. I thought you were answering your own question for a moment there.</p>
<p>:P it used to be a nickname of mine</p>
<p>as for why bigb85 has the same name, i'm not too sure.</p>
<p>lol. i was like "why is he explaining it to himself o<em>o"
apparently, Big B is either an indian actor, a movie, a rapper, or a type of drug. lol
Big B - Wikipedia, the free encyclopedia</p>
