She was unable to salvage 4.8% of the total number of samples. If she was able to salvage 12 of the 24 improperly stored samples, then she was unable to salvage 12 of them. Divide the number that was not salvaged (12) by the total number of samples (250), then multiply by 100 to get the percentage.
