Answer 1

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

Answer 2

Average output=390KW

Updated percentage=30%

Updated output:-

$\\ \sf\longmapsto 30\%\:of\:390$

$\\ \sf\longmapsto 0.3(390)$

$\\ \sf\longmapsto 117$

New output=390+117=507KW
