Answer:
Total amount spread on electricity in three months is $784.98.
Step-by-step explanation:
Tan's electricity bill for the month of August was $267.00.
It is given that the September bill showed a 2% increase from his August bill.
Increase in electricity bill is 2% of $267.00.
[tex]\frac{2}{100}\times 267=5.34[/tex]
The electricity bill for the month of September is
[tex]267.00+5.34=272.34[/tex]
It is given that in October, his bill decreased 8% from the amount he was billed in August.
decrease in electricity bill is 8% of $267.00.
[tex]\frac{8}{100}\times 267=21.36[/tex]
The electricity bill for the month of October is
[tex]267.00-21.36=245.64[/tex]
Total amount spread on electricity is
[tex]Total=267.00+272.34+245.64=784.98[/tex]
Therefore total amount spread on electricity in three months is $784.98.
