In a recent stock market downturn, the value of a $5,000 stock is decreasing at 2.3% per month. This situation can be modeled by the equation A(t) = 5,000(0.977)12t, where A(t) is the final amount and t is time in years. Assuming the trend continues, what is the equivalent annual devaluation rate of this stock (rounded to the nearest tenth of a percent) and what is it worth (rounded to the nearest ten dollars) after 1 year?
24.4% and $3,780.00
75.6% and $3,780.00
27.6% and $1,380.00
72.4% and $3,620.00

Have you considered substituting t = 1 into the equation?
No. I really need someone to talk me through this. I am having a really hard time understanding it @tkhunny
There is no talking through to do.
Problem statement gives: A(t) = 5,000(0.977)^(12t)
Problem statement asks: after 1 year (or t = 1)
Substitute and calculate.
