Quizplus · Accepted Answer

After 10 years, we need to find A(10). Substituting t=10 in the given function, we get A(10) ≈ 605 grams. Rounding to the nearest whole gram, we get the answer as 605 grams. Plug in t = 10 into the given function to find A(10) = 800e^(-0.025*10) ≈ 605. So, after 10 years, there will be around 605 grams left. Rounded to the nearest whole gram, the answer is 605 grams.
