Alight bulb consumes 10200 watt-hours in 4 days and 6 hour. how many watt-hours does it consume per day?

First we can convert 4 days and 6 hours into hours so since theres 24 hours in a day, is 24(4) + 6 = 96 + 6 = 102.
if x is the number of watts per hour, then we can say 102x = 10200. then solve for x, we get x = 100. the multiply that by 24 since there are 24 hours in a day, we get 2400

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
