# Hints ## 1. Determine if you will need a driver's license - Use the [equals comparison operator][comparison-operators] to check whether your input equals a certain string. - Use one of the two [logical operators][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][comparison-operators] 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][if-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][if-statement] as mentioned in the instructions. - In the two if conditions use [comparison operators][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`.
