Solution
Here is a Python program that calculates the amounts of flour, sugar, and butter needed for a different number of cupcakes:
def calculate_ingredients(n):
# Original recipe yields 12 cupcakes
original_yield = 12
# Original quantities of ingredients for 12 cupcakes
original_flour = 2.5
original_sugar = 1
original_butter = 0.5
# Calculate the quantities needed for n cupcakes
flour = round((n / original_yield) * original_flour, 2)
sugar = round((n / original_yield) * original_sugar, 2)
butter = round((n / original_yield) * original_butter, 2)
# Print the quantities
print("Flour: " + str(flour) + " cups")
print("Sugar: " + str(sugar) + " cups")
print("Butter: " + str(butter) + " cups")
# Test the function with different numbers of cupcakes
calculate_ingredients(12)
calculate_ingredients(1)
calculate_ingredients(100)
calculate_ingredients(13)
This program defines a function calculate_ingredients(n) that calculates the amounts of flour, sugar, and butter needed for n cupcakes. It first defines the original yield of the recipe and the original quantities of the ingredients. It then calculates the quantities needed for n cupcakes by multiplying the original quantities by the ratio n / original_yield. The quantities are rounded to two decimal places using the round() function. Finally, the function prints the quantities. The function is then tested with different numbers of cupcakes.
