t + c = 600 1.30t+ 1.20c = 765 Solve the system.

ooo soo all I was missing was the ones on the %s thought my answer was off
Hero
  • Hero
t(1 + .30) = t + .30t = 1.30t c(1+.20) = c + .20c = 1.20c

The markups of course is what allows him to make a profit.
anonymous
  • anonymous
soo is it 1.3t+1.2c=765?
Hero
  • Hero
For the second equation, yes
anonymous
  • anonymous
first equation is t+c=600 then the second one is 1.3t+1.2c=765
Hero
  • Hero
Correct
anonymous
  • anonymous
the profit is 165 not 765
anonymous
  • anonymous
but I know how to solve one equation and pug it into the other=)
Hero
  • Hero
765 is the total amount he will have however.
Hero
  • Hero
If you have $600, then spend it, would reselling and making only $165 back be a profit?
anonymous
  • anonymous
Ya but they're wanting to know how much he paid for the computer not the total profit
Hero
  • Hero
In order to do that, you have to find the value of variable c. In order to find variable c, you have to set up the proper equations.
Hero
  • Hero
Marie, I don't understand why you are disputing my setup.
anonymous
  • anonymous
you set it up right I'm just questioning whether it should be 765 or 165
Hero
  • Hero
It goes back to that same thing I was telling you earlier. If you put 165, it would mean he only made 165 after reselling. Making only 165 after reselling is not a profit because 165 < 600 A profit only exists if x > 600 765 > 600, which is a profit of 165 The first equation represents the amount of each item costs equaling their total cost. The second equation represents the re-sell prices equaling the total amount made including the original amount plus the profit.

7050/11?
Hero
  • Hero
And what might that be?
anonymous
  • anonymous
vs. 1050/11

the first fraction is what I got the first time using your way the second one is my way
Hero
  • Hero
FYI, prices are not given in fractions. Put the answer in decimal form up accurate to two decimal places
Hero

That is not correct: Wolfram provides the correct values: http://www.wolframalpha.com/input/?i=t+%2B+c+%3D+600+and+1.30t%2B+1.20c+%3D+765
anonymous
  • anonymous
okay lol I trust you lol I won't argue next time
anonymous
  • anonymous
My book says 450
Hero
  • Hero
Yeah, I originally mixed up the variables at the beginning. But 450 and 150 are the answers. If you wanted to nitpick at me, you should have nitpicked me for mixing up the variables :P
Hero
  • Hero
It was supposed to be: c + t = 600 1.30c+ 1.20t = 765 That's the only mistake I made.
Hero
  • Hero
But everything else is right.
