For a dozen eggs, it charges $3.25, and for individual eggs that are not part of a dozen, it charges 45 cents each egg. Using the following phrasing, write a program that prompts a user to enter the number of eggs in the order and then displays the amount owed along with a detailed explanation of why the amount is due: You placed an order for 27 eggs. There are 2 dozen eggs at $3.25 per dozen and 3 loose eggs at 45 cents each, which adds up to a total of $7.85.arrow_forward
