Crash Course on Python Expression and Variables Practice Quiz Solution

Question 1

1. This code is supposed to display "2 + 2 = 4" on the screen, but there is an error. Find the error in the code and fix it, so that the output is correct.

print("2 + 2 = " + str(2 + 2))

# print("2 + 2 = {}".format(2 + 2))

# print(f"2 + 2 = {2 + 2}")

Question 2

In this scenario, two friends are eating dinner at a restaurant. The bill comes in the amount of 47.28 dollars. The friends decide to split the bill evenly between them, after adding 15% tip for the service. Calculate the tip, the total amount to pay, and each friend's share, then output a message saying "Each person needs to pay: " followed by the resulting number.

bill = 47.28

tip = bill * 15/100

total = bill + tip

share = total/2

print("Each person needs to pay: " + str(share))

 Each person needs to pay: 27.186
