Task 3:
The InstantRide Finance team wants to know the average discount amounts for each car in the InstantRide. Calculate the average discount amount as monetary value for the travels where a discount is applied. You need to create a subquery over the TRAVELS table to retrieve CAR_ID and DISCOUNT_AMOUNT, calculated with 2 decimals using the ROUND function.
To calculate the DISCOUNT_AMOUNT, multiply the TRAVEL_PRICE by the TRAVEL_DISCOUNT where the TRAVEL_DISCOUNT value is not NULL. Round the result to 2 decimals.
Then you can use this subquery to get the CAR_ID and AVG of DISCOUNT_AMOUNT values, once again using the ROUND function on the average results. Group the results by the CAR_ID. Use CAR_ID and DISCOUNT_AMOUNT as column aliases and return it back to the Finance team.
Task: Calculate the average discount for each car.
