I have a 7.875 kilowatt system and I get paid. 25 cents per Watt. How much did I earn?

I earned $19.70

Step-by-step explanation:

Given that:

I have 7.875 kilowatt

Convert kilowatt to watt

1 kilowatt = 1000 watt

∴ 7.875 x 1000 watt = => 7875 watt

I get paid 0.25 cents for every watt.

∵ earning = watt system x amount paid

= 7875 x 0.25

= 1,968.75 cent

converting the cent to dollars

since 1 dollar = 100 cent

∴ 1,968.75 cent / 100 cent

= $19.6875

≈ $19.70
