The following situation can be modeled by a linear function. Write an equation for the linear function and use it to answer the given question. Be sure you clearly identify the independent and dependent variables. Then briefly discuss whether a linear model is reasonable for the situation described. The price of a particular model car is $14,000 today and rises with time at a constant rate of $860 per year. How much will a new car of this model cost in 3.8 years?
