Analysis of these rocks indicated that 88.7 % of the original amount of the potassium-40 was still present. The decay model for potassium-40 is Upper A equals Upper A 0 e Superscript negative 0.52912 t Baseline comma where t is in billions of years. Let Upper A equals 0.887 Upper A 0 in this decay model and estimate the age of the bones of the dinosaur.
