If a household's electric consumption is 500 kWh in a month and the rate per kWh is $0.10, what is the total electric bill for that month?

• $50

• $500

• $5

• $0.50

Answer explanation

To calculate the total electric bill for the month, you multiply the electric consumption (in kWh) by the rate per kWh.

Given:

• Electric consumption: 500 kWh

• Rate per kWh: $0.10

Total electric bill = Electric consumption × Rate per kWh

Total electric bill=500 kWh×$0.10/kWh

Total electric bill=500kWh×$0.10/kWh

Total electric bill=$50Total electric bill=$50

So, the correct answer is:

a) $50
