ini cara ngitung nya gimana?

Lampu = 4 * 10 * 10 = 400 W
TV = 2 * 150 *12 = 3600 W
Kulkas = 1 * 200 * 24 = 4800 W

400W + 3600W + 4800W = 8800 W / 8,8 kWh

Total Bayar = 8,8 kWh * 500 * 30
                   = Rp 132.000

Kalau salah maaf ya~

lampu = 4 × 10 × 10 = 400
TV = 2 × 150 × 12 = 3600
Kulkas = 1 × 200 × 24 = 4800

400 + 3600 + 4800 = 8800

biaya = 8800 × 500 × 30
= 44000×30
= 1320000
= 1320 kwh

semoga membantu
