Write an algorithm that is given your electric meter readings (in kilowatt-hours) at the beginning and end of each month of the year. The algorithm determines your annual cost of electricity on the basis of a charge of 6 cents per kilowatt-hour for the first 1,000 kilowatt-hours of each month and 8 cents per kilowatt-hour beyond 1,000. After Modify the test-averaging algorithm of Exercise 3 so that it reads in 15 test scores rather than 4. There are 14 regular tests and a final examination, which counts twice as much as a regular test. Use a loop to input and sum the scores. Modify the sales computation algorithm of Exercise 4 so that after finishing the computation for one item, it starts on the computation for the next. This iterative process is repeated until the total cost exceeds $1000.printing out your total annual charge, the algorithm also determines whether you used less than 500 kilowatt hours for the entire year and, if so, prints out a message thanking you for conserving electricity.
