An airline describes airfare as follows. A normal ticket's base cost is $300. Persons aged 60 or over have a base cost of $290. Children 2 or under have $0 base cost. A carry-on bag costs $10. A first checked bag is free, second is $25, and each additional is $50. Given inputs of age, carry-on (0 or 1), and checked bags (0 or greater), compute the total airfare. Hints: First use an if-else statements to assign airFare with the base cost Use another if statement to update airFare for a carryOn Finally, use another if-else statement to update airFare for checked bags Think carefully about what expression correctly calculates checked bag cost when bags are 3 or more

Answer:

The program in Python is as follows:

age = int(input("Age: "))

carryOn = int(input("Carry on Bags [0 or 1]: "))

checkedBags = int(input("Checked Bags [0 or greater]: "))

airFare = 300

if age >= 60:

   airFare = 290

elif age <= 2:

   airFare = 0

if carryOn ==  1:

   airFare += 10

if checkedBags ==  2:

   airFare += 25

elif checkedBags >  2:

   airFare += 25 + 50 * (checkedBags - 2)

print("Airfare: ",airFare)

Explanation:

This gets input for age

age = int(input("Age: "))

This gets input for carry on bags

carryOn = int(input("Carry on Bags [0 or 1]: "))

This gets input for checked bags

checkedBags = int(input("Checked Bags [0 or greater]: "))

This initializes the base cost to 300

airFare = 300

This updates the base cost to 290 for adults 60 years or older

if age >= 60:

   airFare = 290

This updates the base cost to 0 for children 2 years or younger

elif age <= 2:

   airFare = 0

This updates the airFare if carryOn bag is 1

if carryOn ==  1:

   airFare += 10

if carryOn bag is 0, the airFare remains unchanged

This updates the airFare if checkedBags is 2. The first bag is free; so, only the second is charged

if checkedBags ==  2:

   airFare += 25

This updates the airFare if checkedBags greater than 2. The first bag is free; so, only the second and other bags is charged

elif checkedBags >  2:

   airFare += 25 + 50 * (checkedBags - 2)

if checkedBags is 0 or 1, the airFare remains unchanged

This prints the calculated airFare

print("Airfare: ",airFare)
