A light bulb consumes 9900 watt-hours in 5 days and 12 hours. How many watt-hours does it consume per day?
1 answer:
5 days and 12 hours = 132 hours
9900 total watts / 132 hours = 75 watts per hour
Since the light bulb consumes 75 watts an hour, we need to multiply 75 watts by 24 hours, to figure out how many watts are consumed in a day.
75 watts per hour x 24 hours = 1,800 watt-hours per day

X=number total of student at the school.
70% of x=161
can suggest this equation:
(70/100)x=161
0.7x=161
x=161/0.7=230
Answer: the school has 230 students
