By measuring the amount of carbon-14 in an object, a paleontologist can determine its approximate age. The amount of carbon-14 in an object is given by y = ae 0. 00012 t, where a is the amount of carbon-14 originally in the object, and t is the age of the object in years. A fossil of a bone contains 32% of its original carbon-14. What is the approximate age of the bone? Answer

A new truck that sells for \$29, 000 depreciates 12% each year. What is the value of the truck after 7 years? Answer

\$11, 851. 59
