## On the Subject of Waste Management

Fun fact — The amount of food wasted in Singapore is equivalent to every household throwing two bowls of rice away every day, per annum.

This module features eight buttons, four of which are Roman numerals labeled “I", "V", "X", and "L” which have the values of one, five, ten, and fifty respectively, two with the letters “W (waste) and R (recycle)”, and the last two colored red and green respectively. The red button resets the current stage, and the green button submits the answer. Lastly, there is a display which shows, in the order of submission: Paper, Plastic and Metal. Note: Since the module registers single presses, the correct value for 4 would be IIII and not IV. Similarly, IX would be VIIII. Etc.

To solve the module, the defuser needs to waste and recycle the correct amount of paper, plastic, and metal.

Starting from zero for all values, use the following tables to determine the amount of paper, plastic, and metal present. **Follow all rules until the end of each table, performing an operation for each material type where necessary.**
