Power = current x voltage
So the power is 7 x 110 = 770 W = 0.77kW
0.77 x 13 = 10.01 kWh
10.01 x 10 cents = 100.1 cents (is this 1 dollar? Idk I use a different currency)

I hope this helps you! :)
Answer:
The minimum power neccesary is:
Explanation:
The water is bring to a boil so it goes from 25°C to 100°C, the temperature rise si:
Considering that the cup is always at the same temperatura as the water the trasfered energy can be calculated as:
We have that:
So:
Given that this energy was supplied in 2 minutes:
The minimum power neccesary is:
