the question states "Rating Factors" but may be better stated as Risk Factors. given that a 17 year-old male is a high driving risk factor (of 3.xx, i'm unable to see the image wording cause upon answering the image got smaller) and a 21 to 24 year old male has a risk factor of 2.15, i'm making the assumption on terminology that the "annual base premium" of $879 is multiplied by the risk factor of 2.15 to provide a total due amount of $1,889.85.
