To find out which type of cracker has less sodium per cracker, we need to compare the ratios of milligrams of sodium to the number of crackers for each type of cracker.
For Cracker 1:
Ratio = milligrams of sodium / number of crackers
For the first data point, the ratio is: 520 mg / 20 crackers = 26 mg/cracker
For the second data point, the ratio is: 1040 mg / 40 crackers = 26 mg/cracker
For the third data point, the ratio is: 1560 mg / 60 crackers = 26 mg/cracker
For the fourth data point, the ratio is: 2080 mg / 80 crackers = 26 mg/cracker
For the fifth data point, the ratio is: 2600 mg / 100 crackers = 26 mg/cracker
For the sixth data point, the ratio is: 3120 mg / 120 crackers = 26 mg/cracker
Therefore, the ratio remains constant at 26 mg/cracker for Cracker 1.
For Cracker 2:
Ratio = milligrams of sodium / number of crackers
For the first data point, the ratio is: 200 mg / 16 crackers = 12.5 mg/cracker
For the second data point, the ratio is: 400 mg / 32 crackers = 12.5 mg/cracker
For the third data point, the ratio is: 600 mg / 48 crackers = 12.5 mg/cracker
For the fourth data point, the ratio is: 800 mg / 64 crackers = 12.5 mg/cracker
For the fifth data point, the ratio is: 1000 mg / 80 crackers = 12.5 mg/cracker
For the sixth data point, the ratio is: 1200 mg / 96 crackers = 12.5 mg/cracker
Therefore, the ratio remains constant at 12.5 mg/cracker for Cracker 2.
Comparing the ratios, we can see that Cracker 2 has less sodium per cracker at 12.5 mg/cracker, compared to Cracker 1 which has 26 mg/cracker.
