A light bulb consumes 17100 watt-hours in 4 days and 18 hours. How many watt-hours does it consume a day?

Since one day equals 24 hours, we have:
4 days and 18 hours equals:
4(24) + 18 hours
96 + 18 hours
114 hours

Therefore, we have a proportion, where w is the number of watt-hours in a 24-hour period.
17,100 watt-hours/114 hours = w/24

Typing 1711/114 = w/24 into our calculator, we get:
w = 3,600
