Victoria whit used 578 kw-hr of electricity in December the rate is 9.1 cents per kw-hr find the amount of her electric bill

MatroZZZ [7]

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:

$Amount\ of\ electric\ bill=Electricity\ used\times rate\ of\ electricity$

$Amount\ of\ electric\ bill=578\ kwh\times 9.1\ cents$

$Amount\ of\ electric\ bill=5259.8\ cents.$

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.
