Exponential growth model is:
$P = e^{rt}$

r = .043
P = 2, this is double if initial population is 1

$2 = e^{.043t}$

Solve for t.
Take log of both sides
$ln(2) = ln(e^{.043t}) = .043t \\ \\ t = \frac{ln(2)}{.043}$

16,000 pounds

Step-by-step explanation:

1 ton = 2,000 pounds

If you have 8 tons, that's 2,000 8 times (2,000 x 8) which is 16,000
