The x is the part of y and you have to multiply 1+1 lol
I don't either it is quite hard to be fair
(0.300 kW) * (24 h/day) * (30 day) * ($0.07/kWh) = $15.12
You multiply each by four to get the next number.
2*4=8
8*4=32
32*4=128
The next one in sequence would be 512. Since 128*4=512
That is to take the number rounded to the nearest value to two numbers to the right of the decimal:
5.62
