A sample of 900 g of lead-210 decays to polonium-210 according to the function given by A(t) = 900e ^ (- 0.032t) where t is time in years. What is the amount of the sample after 50 years to the nearest g)?
Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
