Initially the consumption is 162,000 kW per day, after the reduction in production the consumption is 72,000 kW per day.
How to find the energy consumption?
Here we have 3 machines, each consume 4500 kW per hour, and these are on 12 hours per day, son the expected consumption is given by the product:
E = 3*4500 kWh*12h
E = 162,000 kW
After the reduction in the production, only 2 machines are used and 8 hours per day, then the energy consumption now is:
E' = 2*4500kWh*8h = 72,000 kW
Complete question:
"un taller comprueba q 3 de sus máquinas consumen 4500 kWh, funcionando 12h al dia. Al reducirse la producción,solo tiene dos maquinas operando 8 h al dia.Cual es el consumo esperado y cual es el consumo al reducirse la produccion?"
