Hints

1. Determine if you will need a drivers licence

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

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

Start with determining the percentage 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 relational operators to compare the car's age 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.
