Answer:
$2.40
Explanation:
the unit electricity bill is kilo watt hour.
The 60-watt light bulb has a 400 hour life expectency means it will consume
60×400/1000 = 24 KWh units of electricity. Let us suppose each unit of electricity costs is 10 cents.
Then 24×10 = 240 cents = $2.40
Answer:
Explanation:
The following program is written in Java. Using the program code from Purchase class in 5.13 I created each one of the fruit objects. Then I set the price for each object using the setPrice method. Then I set the number of each fruit that I intended on buying with the setNumberBought method. Finally, I called each objects getTotalCost method to get the final price of each object which was all added to the totalCost instance variable. This instance variable was printed as the total cost of the bill at the end of the program. My code HIGHLIGHTED BELOW
//Entire code is in text file attached below.
//MY CODE HERE
DecimalFormat df = new DecimalFormat("0.00");
oranges.setPrice(10, 2.99);
oranges.setNumberBought(2*12);
eggs.setPrice(12, 1.69);
eggs.setNumberBought(2*12);
apples.setPrice(3, 1);
apples.setNumberBought(20);
watermelons.setPrice(1, 4.39);
watermelons.setNumberBought(2);
bagels.setPrice(6, 3.50);
bagels.setNumberBought(12);
totalCost = oranges.getTotalCost() + eggs.getTotalCost() + apples.getTotalCost() + watermelons.getTotalCost() + bagels.getTotalCost();
System.out.println("Total Cost: $" + df.format(totalCost));
}
}
