Solve the problem.The function A = Aoe-0.01155t models the amount in pounds of a particular radioactive material stored in a concrete vault, where t is the number of years since the material was put into the vault. If 700 pounds of the material are placed in the vault, how much time will need to pass for only 441 pounds to remain? Round to the nearest year.
