Answer:

14256 pence

Step-by-step explanation:

Cost of electricity of a bill for 1 unit= 13.2 pence

Number of units used by Tanya in one week= 90 units

Total number of units in 12 weeks= 90×12= 1080 units

Cost of 1080 units= 1080×13.2= 14256 pence

Hence the total cost of a bill= 14256 pence

Hence, the correct answer is 14256 pence.
