## Crypto Miner

Consider a 120 Watt computer graphics card is plugged into a 220 volt circuit. The GPU is used to mine a cryptocurrency overnight for 720 minutes. If the energy company charges 10 cents per KW∙hr, how much did it cost to run the miner overnight?

**Hint**

The electrical power is billed in
$$kW\cdot hr$$
, so first determine the energy usage:

$$$120W\cdot 720min\cdot \frac{1hr}{60min}=1440\:W\cdot hr$$$

**Hint 2**

To calculate the cost, simply multiply the energy usage by the rate.

The electrical power is billed in
$$kW\cdot hr$$
, so first determine the energy usage:

$$$120W\cdot 720min\cdot \frac{1hr}{60min}=1440W\cdot hr=1.44kW\cdot hr$$$

To calculate the cost, we can simply multiply the energy usage by the rate:

$$$1.44kW\cdot hr\times10\frac{cents}{kW\cdot hr}=14.4\:cents$$$

It would cost 14.4 cents or $0.14 to run the mining rig overnight.
