You are in charge of supplying beer to the second edition of the Monterrey City Limits (MCL) music festival. In its initial edition, the festival lasted 1 day and had an attendance of 15,000 people.

This year, the MCL will last for 2 days and expect an attendance of 20,000 on the first day and 25,000 on the second day. The cost of the ticket (which is a pass that includes both days) is $ 1,000 MXN. A total of 60 bands and some DJs will play at the festival, on 5 stages playing simultaneously from 11 AM to 1:30 AM on both days. The type of music comprises several genres including: alternative rock, funk, rock in Spanish, electronic and dubstep.

For this festival, Cervecera Cuauhtmoc will supply two sizes of bottles (medium and loggerhead). To supply the beer festival, you agreed with a Cervecera Cuauhtmoc salesperson to send him the number of double semi-trailers (see photo) you need and the mix of beer sizes you need. To achieve this, you must answer the following points:

Demand for beers (30 min)

Estimate how many medium-sized and loggerhead beers (in units and liters) will be consumed at the MCL festival. Assuming that the average price is $ 40 MXN and the price of the loggerhead is $ 70 MXN.

Number of double semi-trailer trucks (10 min)

Estimate how many double semi-trailer trucks are required to supply the festival's beer demand in the two days.
