Below is the weighted decision matrix method for different choices of buying a car. You have $4$ alternative cars $($Alt $1$ through Alt $4).$ The criteria of each car is listed $($they are Color, Gas Mileage, Cost, Type$).$ Your ranking of the criteria are included $($numbers under the criteria... $1$ is poor, $10$ is best$).$ The weights of the criteria are listed as well... $10\%,20\%).$ Simply compute the score of each alternative and identify which Alternative is the best.
