<h2>
Step-by-step explanation:</h2>
Electric power costs 17.8 cents per kWh in Los Angeles in July 2017.
Now we are asked to find the cost to run a 1500 W hair dryer for 10 minutes in Los Angeles during July 2017.
We know that: 1 w=0.001 kW
This means that:
1500 W= 1.500 kW
Also, it is used for 10 minutes
i.e. 1/6 hours
Hence, the electric power used to run the hair dryer is: 1.500×(1/6)
i.e. Electric power to used by hair dryer is: 0.25 kWh
Cost of 1 kwh is: 17.8 cents
This means that cost of 0.25 kwh is: 17.8×0.25
= 4.45 cents
Hence, the answer is:
4.45 cents
