The population of a town grows at a rate
proportional to the population present at
time t. The initial population of 500
increases by 10% in 10 years. What will be
the population in 20 years? (Round your
answer to the nearest person.)

An economist predicts that the cost of food will increase by 4% per year for the next several years.
Part A: Use the economist's prediction to write an explicit rule for a geometric sequence that
gives the cost in dollars of a box of cereal in year n that costs $3.20 in year 1.
Part B: What is the fourth term of the sequence, and what does it represent in this situation?

The GDP of South Africa in 1950 was 77,836.88 million dollars. In 2019 it was 748,861 million dollars. What has been the annualized growth rate of GDP for South Africa during the period 1950 to 2019? Use growth compounding to calculate the number and write the answer in percent terms with up to two decimals (e.g., 10.22 for 10.22%, or 2.33 for 2.33%).
