0.05x+0.12(x+5000)=940 the answer is 2000 but how do you get it? don't you have to multiply by 100?

  • math -

    yes, I would multiply by 100 to get rid of my decimals
    (you don't HAVE to)

    5x + 12(x+5000) = 94000
    5x + 15x + 60000=94000
    17x = 34000
    x = 2000


    .05x + .12x + 600 = 940
    .17x = 340
    x = 340/.17 = 2000
