Question

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 $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 = 5
The two investments will reach the same va
