An online store called Complete Colorguard Equipment sells customized flags for colorguard performances. The store uses a program where the customer inputs the specifics for a flag order. Customers may order poles separately from flags. The program then calculates the total cost of the order. The following input is required:

Do you need a pole? Yes, No

If yes, size? 5ft - 9ft

The pattern on the flag: SOLID, STRIPES, CURVES

The preferred fabric: COTTON, NYLON.

The number of flags to be purchased as an integer: 1-99 inclusive

Each nylon flag costs $15 (tax is included in the price), plus $2 per foot over five feet. Each cotton flag costs $20 (tax is included in the price), plus $2 per foot over five feet.

A discount of %10 is applied to orders of 20 flags or more.

Exercise:
1. Write a list of equivalence classes for the input data to this program.

1. 
   Write a set of test cases to exercise all the equivalence classes. (Include pattern, even though it doesn't affect the price.)

For each test case indicate which classes it covers.
