Question

A light bulb consumes 960 watt-hours per day. How many watt-hours does it consumes in 4 days and 18 hours?

Answer 1

960 watts = 24 hours

4 days = 96 hours

960 (watts) x 4 (days) = 3840 watts

12 hours= 480 watts

6 hours = 240 watts

18 hours = 720 watts

3840 (4 days) + 720 (18 hrs) = 4560
