Answer:

2.56

Explanation:

Multiply by (1+6e^(-.7t))/1000:

2000/1000 = 1 +6e^(-0.07t)

1 = 6e^(-0.07t) . . . . . . . . . subtract 1

e^(0.07t) = 6 . . . . . . . . . . multiply by e^(0.07t)

0.07t = ln(6) . . . . . . . . . take the natural log

t = ln(6)/0.07 . . . . . . . divide by the coefficient of t

t ≈ 2.55966 ≈ 2.56
