Let C be the average cost per kwh. 
Then, according to the given information:
11ec1e8e_2c02_4be9_be9b_8f2806371860_TBX8967_11 + 0.11(11ec1e8e_2c02_4beb_be9b_df47ecc89d28_TBX8967_11)= 11ec1e8e_2c02_4bec_be9b_b7930e383e24_TBX8967_11 + 11ec1e8e_2c02_4bea_be9b_5b06cfa8928f_TBX8967_11(11ec1e8e_2c02_4be9_be9b_8f2806371860_TBX8967_11/11ec1e8e_2c02_4beb_be9b_df47ecc89d28_TBX8967_11)= 11ec1e8e_2c02_4bed_be9b_fbc811a460ff_TBX8967_11 + 11ec1e8e_2c02_4bea_be9b_5b06cfa8928f_TBX8967_11(C)
Simplifying the above equation, we get:
C = 11ec1e8e_2c02_4bed_be9b_fbc811a460ff_TBX8967_11 = 0.11. 
Therefore, the average cost per kwh when 11ec1e8e_2c02_4beb_be9b_df47ecc89d28_TBX8967_11 kwh are used is 11ec1e8e_2c02_4bed_be9b_fbc811a460ff_TBX8967_11 or 0.11 cents.
