    Hi there, this was helpful, however i am confused as to how 2 of the figures were calculated. They are:
    $152.50 for labour
    $22.50 for materials
    I can’t see how were these figures calculated. Could anyone help?
    Thank you

      HI MAN !

      5s=181 – (6*4.75)
      5s= 152.5
      s=152.5/5 = 30.5.


      5s + 10e = 202.5
      (5s)+(6e)= (180)
      0 + 4e = 22.5
      e = 22.5/4 = 5.625.

      hope it s not too late
