Question 1120704: Country A has a growth rate of 4.8% per year. The population is currently 4,274,000, and the land area of Country A is 20,000,000,000 square yards. Assuming this growth rate continues and is exponential, after how long will there be one person for every square yard of land?
I have no clue how to start this. Can anyone help?

-----
P(t) = 4,274,000*(1.048)^t
-----
Solve:: 4,274,000*1.048^t = 20,000,000
---
1.048^t = 4.67946
---
t = log(4.67946)/log(1.048)
-----
t = 32.9 yrs
