1 color

1–99 shirts: RM18 per T-shirt

100–249 shirts: RM16 per T-shirt

250 or more shirts: RM15 per T-shirt

2 colors

1–99 shirts: RM19 per T-shirt

100–249 shirts: RM17 per T-shirt

250 or more shirts: RM16 per T-shirt

3 colors

1–99 shirts: RM20 per T-shirt

100–249 shirts: RM18 per T-shirt

250 or more shirts: RM17 per T-shirt

 

Write a program in which a user can enter the number of T-shirts they would like to be printed and with how many colors (1, 2, or 3). Calculate the cost based on the company’s rates and include UPrint sales and use tax of 6%. Print this total ringgit amount to the screen, formatted to two decimal places. Here is a demo of the program.
