A population of 450 animals that decreases at an annual rate of 19%.
2. If $100 is invested at 6% compounded monthly for 7 years the compounded amount is given by Given that log 1.005 = 0.00217, find log A. (Note that 100 = )

A 12% decrease in one year = 88% of initial value
P = (430) (0.88)ⁿ ... where n = years
P(0) = (430) (0.88)º = 430
P(1) = (430) (0.88)¹ = 378
P(5) = (430) (0.88)^5 = 227
