Borrowing from the tradition of the ancient Greeks, the first ones
who tried to describe the brightness of stars with numbers ...

6 magnitudes = a ratio of 100 .

In more modern notation . . .

   1 magnitude = ratio of (100) ^ (1/6)

   = about 2.154...

   9.6 magnitudes = (100) ^ (9.6/6)

   = 100¹·⁶

   =   1,584.89 (rounded)

B. Energy

A power company charges its customers for electricity based upon B. Energy.

<h3>Explanation:</h3>

Kilo-watt Hours (kWh) is the unit that measures the electricity consumption of customers. Since Power is defined as the rate at which electrical energy is transferred by an electrical circuit per unit time,

$P = \frac{E}{t} \\E= P\times t$

If energy is transmitted at a constant rate over a period of time, the total energy in kilowatt hours is the product of power in kilowatts(kW) and time in hours (h)

$1\ kWh = 3.6\times 10^6\ Joules$
