I am working on a pricing sheet for regular and premier classes. Regular
classes are $9/class and Premier are $14/class. If the customer takes classes
they would get a 10% discount off the 2nd class, if they take 3 classes they
get 10% off the 2nd and 20% off the 3rd, 4th, 5th, etc. If cust take 3
classes and 2 are Premier then it would be something like this,
Pre+Pre-(Pre*.10)+reg-(reg*.20). They pay the premier price 1st, the lower
discount on the 2nd premier class and then the 20% off the regular class.
But when you mix things up thats when I get really confused. I have too many
if/and statements, there has got to be a better way.

Rates Class Type
Customer Type Regular Premier
Regular Rate (REG) $9.00 $14.00
Min Rate $6.75 $10.00
Number of Weeks 8
Regular Rate Discounts for Multiple Classes (REG)
Disc. for 2 10.00% 10.00%
Disc. for 3+ 20.00% 20.00%
Name Reg 1 Reg 2 Reg Cls Prem1 Prem2 Prem Cls Total Name 1 2 1 3 2 1 3 6
Name 2 2 0 2 1 1 3

So for client 1 taking 3 regular classes and 3 premier classes it would be
56.65, or 14+11.90+10.50+(3*6.75)
For Client 2 taking 2 reg classes and 1 premier it would be 28.67 or
14+7.92+6.75.
