Answer:

  • 507 KW/h

Step-by-step explanation:

Initial output:

  • 390 KW/h

Upgraded output:

  • 30% more

Find the upgraded output in number:

  • 390 + 30% of 390 =
  • 390 + 390*30/100 =
  • 390*1.3 =
  • 507

Average output=390KW

Updated percentage=30%

Updated output:-

[tex]\\ \sf\longmapsto 30\%\:of\:390[/tex]

[tex]\\ \sf\longmapsto 0.3(390)[/tex]

[tex]\\ \sf\longmapsto 117[/tex]

New output=390+117=507KW
