Solve the problem.The formula A = P + Prt represents the value, A, of an investment of P dollars at a yearly simple interest rate, r, for t years. The equation to model the value, A, of an investment of $97 at 5.15% for t years is given by A = 97 + 5t. The equation to model the value, A, of an investment of $101 at 3.96% for t years is given by A = 101 + 4t. Assuming A has the same value, the given equations form a system of two linear equations. Solve this system using an algebraic approach and interpret your answer.

A. t = 5; The two investments will reach the same value in 5 years. B. t = 400; The two investments will reach the same value in 400 years. C. t = 4; The two investments will reach the same value in 4 years. D. t = 8; The two investments will reach the same value in 8 years.
