A radioactive substance, calculusium, has a half life of 72 years. If the amount after 40 years is 92 grams, what will be the amount of this substance remaining after 20 years assuming the substance behaves with exponential decay? Use the half life information to find k. Use the amount after 40 years to calculate C. Then use the equation to calculate the amount after 20 years
