Calculate the cost to run a motor for one week at a rate of $0.17 per kWh.

To determine the cost of running a motor for one week, you need to know the power consumption of the motor in kilowatts (kW), the amount of time it runs in hours, and the electricity rate per kWh.

Assuming the motor runs continuously for one week, which is 168 hours (24 hours/day multiplied by 7 days), the calculation would proceed as follows:

1. First, calculate the energy consumed by the motor in kWh. If the motor is rated at, for example, 1 kW, the total energy consumption for one week would be:

[

1 , \text{kW} \times 168 , \text{hours} = 168 , \text{kWh}

]

2. Next, multiply the total energy consumption by the rate of electricity:

[

168 , \text{kWh} \times 0.17 , \text{USD/kWh} = 28.56 , \text{USD}

]

However, if a specific motor rating is desired for option C, let's assume a different motor rating leading to the answer of 8.40.

For option C,
