To determine which type of cracker has less sodium per cracker, we need to calculate the amount of sodium per cracker for each type of cracker.

Cracker 1:

  • For 20 crackers: 520 mg / 20 = 26 mg/cracker
  • For 40 crackers: 1,040 mg / 40 = 26 mg/cracker
  • For 60 crackers: 1,560 mg / 60 = 26 mg/cracker
  • For 80 crackers: 2,080 mg / 80 = 26 mg/cracker
  • For 100 crackers: 2,600 mg / 100 = 26 mg/cracker
  • For 120 crackers: 3,120 mg / 120 = 26 mg/cracker

Cracker 2:

  • For 16 crackers: 200 mg / 16 = 12.5 mg/cracker
  • For 32 crackers: 400 mg / 32 = 12.5 mg/cracker
  • For 48 crackers: 600 mg / 48 = 12.5 mg/cracker
  • For 64 crackers: 800 mg / 64 = 12.5 mg/cracker
  • For 80 crackers: 1,000 mg / 80 = 12.5 mg/cracker
  • For 96 crackers: 1,200 mg / 96 = 12.5 mg/cracker

Now let's compare the sodium content per cracker:

  • Cracker 1 has 26 mg of sodium per cracker.
  • Cracker 2 has 12.5 mg of sodium per cracker.

Conclusion: Cracker 2 has less sodium per cracker.
