Question

A used-car dealership has hired you to modify the price of cars that are up for sale. In a script, assign the initial information about the car to a structure called carInfo.

The structure shall have the following fields:

ID: An identification number for the vehicle

Make: A string that represents the make of the car

Year: A number that corresponds to the year of the car

Price: A number that holds the marked price of the car

Miles: The number of miles clocked

Accidents: The number of accidents the car has been in

Write a user-defined function called usedCar that receives the structure carInfo and changes each cars price depending on a number of factors.

The function should return the structure with the following adjustments to the price field.

1. Add $2,500 to the price, if the car has clocked less than 15,000 miles.

2. Reduce the price by $1,000 if it has clocked more than 190,000 miles.

3. Reduce the price by $1500 for each accident.

Run the script with the following input data set:

ID	Make	Year	Price ($) (prior to modification)	Miles	Accidents
299	Volvo	2016	40,000	10,000	0
132	Subaru	2003	6,000	200,000	2

Answer 1

%function file

function carInfo = usedCar(carInfo)
if carInfo.Miles<15000
    carInfo.Price=carInfo.Price+2500;
elseif carInfo.Miles>190000
    carInfo.Price=carInfo.Price-1000;
end
carInfo.Price=carInfo.Price-1500*carInfo.Accidents;
