Answer:
The amount of electricity bill is <u>$52.60</u>.
Step-by-step explanation:
Given:
Victoria whit used 578 kwh of electricity.
The rate is 9.1 cents per kw-hr.
Now, to find the amount of her electric bill.
Electricity used = 578 kwh.
Rate of electricity = 9.1 cents per kw-hr.
So, to get the amount we multiply the electricity used by the rate of electricity:
Thus, the amount of electricity bill = 5259.8 cents.
Now, converting the amount from cents to $ by dividing:
$1 = 100 cents.
So, 5259.8 cents ÷ 100 = $52.60 .
therefore, the amount of electricity bill is $52.60.
