Answer 1

[(3×20×12) + (3×40×12) + (350×2) + (250×24)] × 30 × 600 ÷ 1000
= (720 + 1440 + 700 + 6000) × 18
= 8860 × 18
= 88600 + 70880
= RP 159480

Answer 2

3×20×12=720⇒ 3×40×12=1440⇒ 350×2=700⇒ 250⇒ Beabn daya = 720+1440+700+250=3110watt×30hari=93300watt=93,3kwh⇒ Biaya yg hrs dbyr = 55980 Jd yg hrs d byr selama 1 bln, Rp. 55.980,00 Smoga membantu ^^
