Answer:

3days12

Given that a light bulb consumes 960 watt-hours per day, this can be expressed as:

960 watt-hours = 1 day

In order to get the time it takes to consume 3360 watt-hours, this can be expressed as:

3360 watt-hours = x

Divide both expressions

$\begin{gathered} (960)/(3360)=(1)/(x) \\ 960x=3360 \\ x=(3360)/(960) \\ x=3.5\text{ days} \end{gathered}$

Convert to days and hours

Note that 1 day = 24 hours

0.5 day = 12 hours

Hence the time it will take to consume 3360 watt-hours is 3 days 12 hours
