The light bulb consumes
[tex]960\text{watt}-\text{hour in one day}[/tex]To calculate how long 5520 watt-hours would last, we will use the formula below
[tex]\text{time}=\frac{Number\text{ of watts hour to be used}}{\text{Number of watts hour per day}}[/tex][tex]\begin{gathered} \text{Time}=\frac{5520}{960} \\ \text{Time}=5\frac{3}{4}days \end{gathered}[/tex]Which can be converted as
[tex]\begin{gathered} 5\frac{3}{4}days=5+\frac{3}{4}\times24 \\ 5\frac{3}{4}days=5\text{days 18 hours} \end{gathered}[/tex]Hence,
It will take 5 days and 18 hours to consume 5,520 watt-hours
