A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that result from the fat using the following formula: Calories from fat = Fat grams times 9 Next, she calculates the number of calories that result from the carbohydrates using the following formula: Calories from carbs = Carbs grams times 4 Create an application that will make these calculations. In the application, you should have the following methods: FatCalories-This method should accept a number of fat grams as an argument and return the number of calories from that amount of fat. CarbCalories-This method should accept a number of carbohydrate grams as an argument and return the number of calories from that amount of carbohydrates Write a program that asks the user to enter an item's cost and its markup percentage. It should then display the item's retail price. For example: If an item's wholesale cost is $5.00 and its markup percentage is 100 percent, then the item's retail price is $10.00. If an item's wholesale cost is $5.00 and its markup percentage is 50 percent, then the item's retail price is $7.50. The program should have a function named calc that receives the wholesale cost and the markup percentage as arguments and returns the retail price of the item
