A. The equation that represents the price, e, of the electricity is e + 0.05e + 6.30 = 48
C. The cost of the electricity before taxes or fees is $39.71. 

e + 5% of e + 6.30 = 48
e + 0.05e + 6.30 = 48
1.05e = 48 - 6.30
1.05e = 41.70
e = 39.71

39.71 + 5%(39.71) + 6.30 = 48
39.71 + 1.99 + 6.30 = 48
48 = 48
