equation to model the value, A, of an investment of $54 at 9.26% for t years is given by
A = 54 + 5t.
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 = 5The two investments will reach the same value in 5 years.
c.t = 1000
The two investments will reach the same value in 1000 years.
b.t = 20
The two investments will reach the same value in 20 years.
d.t = 10

Question
