a) 11.283 dollars
b) 1.435 hour
Step-by-step explanation:
1 kilo watt of electricity used for 1 hour
Charges of electricity per unit = $0.05224
Laura uses 5 heaters to warm her house. The electricity consumed by each use 1800 wats or 1.8 kilo wats
a) Charges in one day = 5 heaters * 1.8 kilo wats per hour * 24 hour* $0.05224 per kilowats per hour
= 11.283 dollars
b) 75 wat light bulb consumes 0.075 kilo wats per hour
Charge per kilowat per hour = $0.05224
In order to cost 1 $, the 75 wat bulb need to be on for 1.435 hour
