bonjour
la TVA est de 20 %
20 x = 3.96 * 100 = 396
396 / 20 = 19.8 €
1 kWh = 0.12 donc 19.8 / 0.12 = 165 kWh
consommation = 165 kWh
(14 * 5.5 ) / 100 = 0.77 donc 14 + 0.77 = 14.77
abonnement TTC = 14.77
19.8 + 3.96 = 23.76
Consommation TTC = 23.76
23.76 + 14.77 = 38.53
montant TTC facture = 38.53 €
