Hints

1. Determine if you will need a driver's license

• Use the equals comparison operator to check whether your input equals a certain string.
• Use one of the two logical operators you learned about in the boolean concept to combine the two requirements.
• You do not need an if-statement to solve this task. You can return the boolean expression you build directly.

2. Choose between two potential vehicles to buy

• Use a comparison operator to determine which option comes first in lexicographical order.
• Then set the value of a helper variable depending of the outcome of that comparison with the help of an an if-else statement.
• Finally construct the recommendation sentence. For that you can use the + operator to concatenate the two strings.

3. Calculate an estimation for the price of a used vehicle

• Start with determining the percentage of the original price based on the age of the vehicle. Save it in a helper variable. Use an if-else if-else statement as mentioned in the instructions.
• In the two if conditions use comparison operators to compare the age of the car to the threshold values.
• To calculate the result, apply the percentage to the original price. For example 30% of x can be calculated by dividing 30 by 100 and multiplying with x.
