Posted by on .

the sale price of a computer at 15% off is $746.30. What is the regular price?

  • math - ,

    OK, Jazz. It's your turn now. :-) How do you think you'd solve that problem?

  • math - ,

    umm.... like claudia did??? :P

  • math - ,

    I'm don't think so. I think she had an error so I deleted her post.

    Besides, I want you to think about this problem. <g>

  • math - ,

    no im just kidding i know.. 0.15 x 746.30?

  • math - ,

    wait.. then u subtract that from the original nubmer??

  • math - ,

    r u still there?? :( did u leavee??

  • math - ,

    I'm still here. I'm not a math teacher so I had to take some time to figure this one out. I'll post again in a couple of minutes.

  • math - ,

    oh ur still here yay!!!!!:D im so happy now!

  • math - ,

    Does 0.15 * 746.30 give you a reasonable number?

    The computer must originally cost more than 746.30.

  • math - ,

    ooo i get it now. so 749.30 x 0.15
    then add that to the original number???

  • math - ,

    Nope.

    100 - 0.15 = 0.85

    0.85x = 746.30
    x = ?

  • math - ,

    aww man i was sure i had it.hehe guess not! good thing u were here.thks so much for all of this!!

  • math - ,

    oh and so x equals 8.78?

  • math - ,

    Come on, Jazz. You're looking for the original price of the computer. It must be over $800. Right?

  • math - ,

    ahh!! im so confused.

  • math - ,

    sorry. not trying to be rude
    but now im confused. :/
    we are working in our class in
    something related to this.

    so wouldnt an increase in 15% be a multiplier of 1.15
    so you do 746.30*1.15= 858.24
    or another way i solve it is
    by doing 746.30*.15=111.94
    so then u add 746.30+111.94
    = 858.24

    so what im i doing wrong.
    why was my answer wrong.
    can you please help. im doing
    homework over this and i dont
    want to get it wrong

  • math - ,

    i have no idea. im so sorry.

  • math - ,

    oh im not talking to u claudia, don't worry. ill try and help but im not so good at this. im sure ms sue could help u though!

  • math - ,

    0.85x = 746.30
    x = ?

    x = 746.3 / 0.85
    x = 878

    The original price of the computer was $878.

    Doesn't that make sense now?

  • math - ,

    ooooooo!!!!! yes that makes perfect sense!! im sorry my brains not working right now.

  • math - ,

    Good night Jazz. Get a good night's sleep and it will look better in the morning. <g>

  • math - ,

    alright thx soo much this was great help u don't no how much this means to me. goodnight!
