Explanation:
Here's the simple and clear rendering of the question:
"One company hired four full-time workers last year, at a cost of €18,000 per year each; used 12,000 units of materials, at a cost of €1.5 per unit. It also used 1,500 hours of machinery, at a cost of €4 / hour. With all these materials, the company produced 1,000 bicycles and 2,000 skateboards. This year, the company reduced the number of workers to three, increased the consumption of material units by 12% and decreased the operation of machine hours by 5%. Production has varied this year, as it obtained 500 bikes and 2,500 skateboards. Knowing that the price of bicycles was €100 last year and that of skateboards €70, calculate the company's productivity each year and calculate and briefly comment on its percentage evolution".
