I am working on a calculation:

Original CostFinal CostMarkupDivisor (Markup)
Lot 154347800.000%.435407
Lot 554347566.00-3%.435407
Lot 1054347410.00-5%.435407
Lot 154348041.240%.479801
Lot 554347800.00-3%.479801
Lot 1054347639.18-5%.479801
Lot 154348210.530%0.51095
Lot 554347964.21-3%0.51095
Lot 1054347800.00-5%0.51095


If I give Lot 1 a Final cost of 7800.00 I can figure out the divisor of .435407 by (7800/5434)-1 = Divisor of .435407
Then I subtract 3% for Lot 5 to come up with 7800-3% = 7566.

To figure out Lot 1 divisor with pricing at 7800 I used the following calculation:
(7800/5434)-1
Then after that I just subtracted 3% from 7800, 5% from 7800, etc.

I figured out the 8041.24 just by typing in numbers randomly into my program until it showed Lot 5 at 7800.

PROBLEM: If I put in 7800 for Lot 5, then how do I calculate the divisor and work my way backwards and forwards. I WANT TO input 7800 for Lot 5, and then have it calculate 8041.24 for Lot 1 and the correct divisor of .479801.

If I put in 7800 for Lot 10, then again, how do I calculate the divisor and work my way backwards and forwards. I WANT TO input 7800 for Lot 10, and then have it calculate 8210.53 for Lot 1 and the correct divisor of .51095

5434*.479801 = 8041.24
(8041.24 - 3% = 7800)

I figured it out!

YES!!! I finally figured it out! OK. You figure for Lot 1 Pricing:

Lot1Price = LotSizePrice / (1 - LotSizeDiscount)
X = 7800 / (1 - 3%)
This gives us Lot1Price = 7800/.97 which is 8041.24

Next you figure the Divisor:
LotDivisor = (Lot1Price / Price) - 1
X=(8041.24 / 5434) - 1
X=.479801 (Which is the Divisor or Markup)

GEESH!!!!!
