ANSWER
[tex]4400W[/tex]EXPLANATION
To find the total wattage that the generator needs to supply, we have to find the sum of the power that all the equipment consumes.
Therefore, we have:
[tex]\begin{gathered} T=1400+2800+100+100 \\ T=4400W \end{gathered}[/tex]That is the total wattage the generator needs to supply.
