So, the total units of electricity in 12 weeks will be: [tex](90*12)=1080[/tex] units
One unit of electricity costs 13.2 pence.
Thus, the total cost for 1080 units will be: [tex](13.2*1080)pence= 14256[/tex] pence.
So, her electricity bill will be of 14256 pence.
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.
