Practice question · Estimate
At 7% continuous growth, the Rule of 70 says doubling time is roughly years. Estimate .
Estimate on a scale from 1 to 3.
Hints
- .
- That is just above 2, which is why the doubling rule works.

Why
, close to 2, confirming the Rule of 70 approximation. At 7% continuous growth, you roughly double in 10 years.
