Write down the function which could be used to estimatethe GDP of a particular country in t years time, when the current GDP equals A units, and which grows at r% per annum, where growth is continuous.

Use this function, estimate the annual average percentage rate of growth r, when GDP of a country grows from 250 units to 420 units in 8 years.

GDP = Ae^8

lnGDP = lnA + lne^8

= 170 + 2980

= 3150

This doesn't look right could someone tell me what im doing wrong?

THanks
