Answer:

Explanation:

5 bulbs of 40W each used for 5hr : 5*40w*5/1000

therefore 5*40*5/1000= 1000/1000=1kwh

electric press for 4 hr and 500w : 4*500*1/1000=2kwh

total energy for 30 days : 1*30 =30 units for bulbs

total energy for electric press for 30 days :2*30=60 units

total energy = 30+60=90units
