Write a program that asks for the number of calories and fat grams in a food. The program should display the percentage of calories that come from fat. If the calories from fat are less than 30% of the total calories of the food, it should also display a message indicating that the food is low in fat. One gram of fat has 9 calories, so Calories from fat = fat grams * 9. The percentage of calories from fat can be calculated as Calories from fat ÷ total calories . Input Validation: Make sure the number of calories and fat grams are not less than 0. Also, the number of calories from fat cannot be greater than the total number of calories. If that happens, display an error message indicating that either the calories or fat grams were incorrectly entered.

Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared. Calculate a persons Body Mass index using their weight in pounds. This means you must first convert pounds to kilograms (kg) then apply the formula above. In converting pounds to kg, 1 pound = 0.453592 kg. So to convert pounds to kg, either multiply the pound value by 0.45359237 or divide by 2.2046226218. Then you must convert their height in inches to meters. The length in meters is equal to the inches multiplied by 0.0254. Write a program that accepts a users height as an integer in inches and their weight in pounds. Convert those inputs to their metric equivalents outlined above and determine their body mass index. Display what the conversions from and to their metric equivalents are. Display the body mass index and the category it belongs to.

QUESTION 8 Kebabo Internet Services offers customers with 600 weekday minutes for a flat rate of RM39.99. Night (8.00 P.M. to 7.00 A.M.) and weekend (Saturday to Sunday) minutes are free, but additional weekday minutes cost RMO.20 each. There are Service taxes (SST) of 6% on all charges. Write a program that prompts the user to enter the number of weekday minutes, night minutes, and weekend minutes used, and calculates the monthly bill and average cost of a minute before taxes.
