If 900 pounds of materials are placed in the vault, how much time would need to pass for only 357 pounds to remain?

The function A = A0e-0.01155x models the amount in pounds of a particular radioactive material stored in a concrete vault, where A0 is the original amount of material and x is the number of years since the material was put in the vault. If 900 pounds of material are placed in the vault, how much time will need to pass for only 357 pounds to remain?
***** 0 should be lower than the A like a subscript
