Calculations through changing box sizes. This is where the vertical counts
can become confusing but as long as you understand the different
calculations for the box sizes, you will be able to do this easily.
Just add the two calculations together.
.50
to 1.00 Box Size
Count
the X's from the bottom X to the change of count. Here it is
four boxes. Do the calculation for the .50 box scale.
4 x 3 = 12 x .50 = 6
Now count the remaining X's, which is 6, and do the calculation for
the 1.0 box scale.
6 x 3 = 18 x 1 = 18.
Add the two totals together.
6 + 18 = 24 + 18.50 = 42.50
Price objective is 42.5.
