Question

PLEASE HELP! I will fan and medal! How much does it cost to run a blow drier for 12 hours in a week if the blow drier runs on 1200 watts and the electric company charges $0.10 per kilowatt hour? (1000 watts = 1 kilowatt)
$14.50
$1.44
$1.15
$2.30

Answer 1

The blow drier consumes 1.2 kilowatts per hour.
That's 1.2*12 kilowatts per week.
The charge per week would be 1.2*12*0.10 dollars
