heres my equation: c(coat)+s(shirt)+t(tie)=$300 c=2s s=2t+40
i need to know how to solve this to get the cost of each item?

  • MATH -

    just substitute the various quantities:

    c+s+t=300
    2s+s+t=300
    3s+t = 300
    3(2t+40)+t = 300
    6t+120+t = 300
    7t + 120 = 300
    7t = 180
    odd that you don't get an exact divisor.
    Oh well, get t and then you can get c and s.
