You are planning on purchasing a new car and have your eye on a specific model. You know that new car prices are projected to increase at a rate of 5% per year for the next few years. Find the cost of the car 3 years from now if the current price is $26,000. Write the equation that represents the projected cost C and provide a solution for the problem.
A. C = 26,000(1.05)(3); $81,900
B. C = 26,000(1.05)3; $30,098.25
C. C = 26,000(3)1.05; $82,404.45
