The equation to model the value, a, of an investment of $84 at 2.38% for t years is given by a = 84 2t. 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 = 20 the two investments will reach the same value in 20 years.
c. t = 1000 the two investments will reach the same value in 1000 years.
d. t = 10 the two investments will reach the same value in 10 years.
