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.
