Question

A light bulb consumes 3600 watt-hours per day. how long does it consume in 3 days and 6 hours?

Answer 1

11700

Explanation:

3600 in one day so 3600 in three days would be 10800 (3600x3)

There are 24 hours in a day so 6 hours would be 1/4 of a day (24/4=6) so 1/4 of 3600 is 900 so

10800+900=11700

11700 = 3600x3 + 3600/4

11700
