Spill Tech specialises in emergency spill response, industrial cleaning, hazardous waste management, contaminated land

rehabilitation, stockpile remediation, liquid fire and marine related services. It has been requested by Transnet to clean tank

storages at the Port of Richards Bay. With standard equipment, the firm typically cleans $70$ tank storages per month. They

utilized $12$ litres of solvent, and two employees worked $20$ days per month, $8$ hours a day. The company decided to switch

to a larger cleaning machine. Last April, they cleaned $60$ tank storages in only $15$ days. They utilized $15$ litres of solvent,

and the two employees worked $8$ hours a day. Using this information determine the raw material and labour productivity with

the standard equipment and the larger equipment. Also comment on the change in productivity when larger cleaning

equipment is introduced. Relevant illustrations should be provided
