The coefficient is: "1" . ____________________________________________________ Note: There is an "<u>implied coefficient</u>" of "1"; since "1", multiplied by any value, is equal to that exact same value; by convention, we eliminate the "1" as a coefficient. ____________________________________ Further explanation: ____________________________________ (x+p)(x−q) = x² − xq + px − pq ; ____________________________________
400$ Explanation: In 1992, the price is 28000$ and 9600$ in 1996 so in 4 years the value the car lost is 18400$ Dividing 18400 by 4 years we get 4600 depreciation value per year. Between 1996 and 1998 there is 2 years So in 1998 the value of the car will be: 9600 (value in 1996) - 2x4600 = 400$
