The sales price of the distribution service is US$ 1.50 / km traveled and its net profit margin is 25% over the total costs. After leaving the annual results meeting, one of the aspects that worries Frank Silvestro, his general manager is that what they have paid for fuel represents 40% of their total operating costs, in Maintenance 25% of these same costs and of this amount, 40% is for the purchase of tires. And 20% in the purchase of oil for the motors of the transport equipment. For this reason, he calls his head of Logistics recently graduated from CEUTEC and asks him to build a table in which he can relate these values to explain how many tires should have been purchased and what was the price at which each one was purchased. Additionally, it asks you to do the same analysis for the purchase of oil. considering that the tires must be changed every 60,000 kilometers and that the oil must be changed every 15,000 kilometers and each articulated equipment consumes 10 gallons and the trucks (C2) consume 5 gallons.
