    I need help trying to figure out equations for a few word problems. i have a test tomorrow and ive been struggling with this for days now, on the verge of tears. Here's the problem: ** Jason paid five times as much for his computer as he did for his printer. He paid a total of $1320 for both items. What did each item cost?**

    all you have to do is translate each word :)

    Right, but when I do and try to put an equation together, it seems impossible to solve.

    I dont want anyone to do my homework for me, I just need help trying to figure out and understand an equation for the word problems.

    Take the first sentence. Choose a variable for how much he paid for his computer and another variable for how much he paid for his printer.

    Right, C=Computer, P= Printer

    Then write the equation given by the first sentence. And a second equation for the second sentence.

    If he pays 4 dollars for the printer. How much did the computer cost?

    Right. So let me rephrase the sentence and you tell me if my version means the same thing.. "The amount Jason payed for the computer was five times what he paid for the printer"

    figure out what C is equal to in terms of P so you can plug that in to your equation with only one variable

    C = 5P ^ Amount for the computer ^ was ^five times the printer

    This is frustrating for me. So I had to switch the C and P?

    That is the first equation. The second equation comes from the next sentence. "He paid a total of $1320 for both items"

    If P is the amount for the printer, and C is the amount for the computer. What is the equation we can infer from this statement?

    C+(5*P)=1320

    If C is the amount you pay for the computer. And P is the amount for the printer. Then the total amount would be C + P

    C+5P would be the amount if you buy 1 computer and 5 printers.

    you know C + P = 1320 right. so replace C with your other equation and solve for P

    You aren't buying 5 of anything. You buy 1 C and 1 P. and the total was 1320.

    Now you can take what you know about C (=5P) and replace C in the equation to find what P is.

    Since C = 5P, 5P + P = 1320

    So there's 2 separate equations because we are trying to figure out 2 different amounts, right?

  48. anonymous

    so the total price of the computer and printer together is 1320 dollars, which means that C + P = 1320....and you know that the computer is five times more expensive than the printer, which is C = 5P.... so if C =5P and C + P =1320, then replace the C in the second equation and you have 5P + P = 1320

    ok, I think I got it. So, how will I be able to solve it? I know I need to figure out what C is first, right?

    There's two equations because there are two different pieces of information given in the problem.

    No, you have 5P + P = 1320. You solve for P

  52. anonymous

    now with that just solve for P... then P is the price of your printer so once you solve for it, the price of your computer is the total price minus the price of the printer

    Ok. I would divide 5 from 1320 which is 244. P=244 Then I would take the 1320 and minus that by 244 to get C. C=1076 Is this correct?

    5P + P = 1320 is the same as 6P = 1320....so you divide 1320 by 6

    Then subtract 220 from 1320 and that equals C C=1100 Is this correct?
