Since the range for the net weight of the cereal is 510(+-) 1.5 grams,
then you can have the net weight as
510 + 1.5 = 511.5 grams    to
510 - 1.5 = 508.5 grams
----------------------------
Since in the first production, the weight is 308 grams, then the weight that should be added to comply with the limits would be
511.5 - 308 = 203.5 grams
508.5 - 308 = 200.5 grams
---------------------------
Therefore it should be increased by 200.5 to 203.5 grams
