Question

a light bulb consumes 960 watt- hours per day. How many watt-hours does it consume in 5 days and 12 hours?

Answer 1

4320


we first need to know how much watt hours are used in 12 hours which we can find by taking 960/2=480 now we just need to take 960*4=3840 and add 480 which gives us our answer of 4320 watt hours.
