I can’t see mc026-1.jpg. Please either type the equation here or paste the image.

If the model is exponential of the common forms, here’s how you’ll solve it once you give the equation:

- If N = a·b^h, set 450 = a·b^h, so h = ln(450/a) / ln(b).
- If N = a·e^{k h}, set 450 = a·e^{k h}, so h = ln(450/a) / k.

Compute h and round to the nearest whole number. Send the equation and I’ll compute which choice (1, 6, 13, or 15) is correct.
