The light bulb consumes


960\text{watt}-\text{hour in one day}

To calculate how long 5520 watt-hours would last, we will use the formula below


\text{time}=\frac{Number\text{ of watts hour to be used}}{\text{Number of watts hour per day}}
\begin{gathered} \text{Time}=(5520)/(960) \\ \text{Time}=5(3)/(4)days \end{gathered}

Which can be converted as


\begin{gathered} 5(3)/(4)days=5+(3)/(4)*24 \\ 5(3)/(4)days=5\text{days 18 hours} \end{gathered}

Hence,

It will take 5 days and 18 hours to consume 5,520 watt-hours
