tolong , kerjakan nomor 2 plsss . trimakasih

lampu = 10 buah 20 W selama 10jam/hari
TV = 150 W selama 8jam/hari
kulkas = 200 W selama 24 jam/hari
harga listrik = Rp 1.000 / kWh
1 bulan = 30 hari
a) 10 × 20 W × 10 jam = 2.000 W = 2 Kw
b) 150 × 8 = 1.200 W = 1,2 Kw
c) 200 × 24 = 4.800 w = 4,8 ke
d) 2 + 1,2 + 4,8 = 8 kw
e) 8 kw × 30 = 240 kw
f) 240 kw × Rp 1.000 = Rp 240.000
