Interest earned: $84
Principal: $600
Interest rate: 7%
Time: ?

2 years

Step-by-step explanation:

The simple interest formula is equal to -  A = P (1  + rt)  Where:

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

In this problem we have:

t = ? years

P = $600

A + $600 + $84 = $684

r = 0.07

A substitute in the formula above would be:

$684 = $600(1 + (0.07)t)

solve for t :

t = [(684/600) - 1]/0.07 = 2 years
