Best ResponseYou've already chosen the best response.2the first one would be interest earned is 72, principal we have to find, rate is .03 and time is 3 years.

Best ResponseYou've already chosen the best response.066(.3)(2) i did this but i got 39.6 :\

Best ResponseYou've already chosen the best response.2\[66=P(.03)(2)\]\[\frac{66}{(.03)(2)}=P\] \[1100=P\]

Best ResponseYou've already chosen the best response.0am I adding the (.03) (2) together and then dividing it by 66?

Mertsj

Best ResponseYou've already chosen the best response.2No. Let's take some simpler numbers and see if you can understand. What if I have 12 = 2x Could you solve that? And how would you do it?

Best ResponseYou've already chosen the best response.2Yes. look at what I am going to draw.

Best ResponseYou've already chosen the best response.2So these equations that you have to solve are exactly like that.

Best ResponseYou've already chosen the best response.2Write this down on a piece of paper; 66=P(.03)(2)

Mertsj

Best ResponseYou've already chosen the best response.2Now multiply .03 times 2

Mertsj

Best ResponseYou've already chosen the best response.2So now write this: 66=P(.06)

Mertsj

Best ResponseYou've already chosen the best response.2Now divide both sides of the equation by .06 like I showed you in the drawing.

Best ResponseYou've already chosen the best response.2Very good. Now set up the next one and tell me how you set it up. NOT the answer, just the setup.

Best ResponseYou've already chosen the best response.2Perfect!! Now, can you solve it?

Best ResponseYou've already chosen the best response.2That's not what I got. You check your answer and I will check mine.

Best ResponseYou've already chosen the best response.0well i got 1800 = p but I did not know what to do with the (2) in 72 = P(.04)(2)

Mertsj

Best ResponseYou've already chosen the best response.2(.04)(2) means .04 times 2 so multiply them together first.

Mertsj

Best ResponseYou've already chosen the best response.2Then you should have 72=P(.08)

Mertsj

Best ResponseYou've already chosen the best response.2Now divide both sides of the equation by .08

Mertsj

Best ResponseYou've already chosen the best response.2Like I showed you in the drawing.

Mertsj

Best ResponseYou've already chosen the best response.2Bingo!!! Now try the last one.

Best ResponseYou've already chosen the best response.072 = P(.04)(2) .04 x 2 = .08 72 = P(.08) 1,900 = p that??

Mertsj

Best ResponseYou've already chosen the best response.2Well that is all perfect except when you divided both sides by .08 you must have hit a wrong button. So try the division part again.

Best ResponseYou've already chosen the best response.2Oh. just a minute. That is the same problem we just did.

Best ResponseYou've already chosen the best response.2The final problem in the list.

Best ResponseYou've already chosen the best response.0seventytwo dollars over 3 years at an interest rate of two percent 72 = P (.02)(3) 72 = P (.06) 1,200 = p
