Jan's Wallpaper Estimating Techniques

Technique #1

steps

___   1.     A / B                                             =       # of strips needed
___   1a.     (A + (I x H))/B                           =       # of strips if centered
___   2.     C + D                                           =       length of each strip
___    3.      step1 x step2                             =       total length needed
___    4.      step3 / E                                     =       approx. #rolls needed
___    5.      F / 2                                            =        openings deduction
___   6.       step4 - step5                              =        final #rolls
___    7.       step6                                          =        rounded up to whole number
___    8.       step7 / K                                    =        #packages (round up)
___    9.       step8 x L x K                            =        price
___   10.      (step7 - step6) x K                   =        slippage extra on last roll
___   11.      (step8 - (step7 / K)) x K          =  #extra rolls
___   12.       6 sq. ft.                                     =  standard slippage allowance
___   13.       36 sq. ft. per single roll          = standard size roll
___   14.       step9 x (100 - m) x .01)          =   discounted price
___   15.       step12 / B                                 =   standard slippage length

            If (step10 - step15) = 0
                       and step 11 = 0
                              step7 = (step7 + 1)
                                    Return to step8
