Answer:

Step-by-step explanation:

So at the start:

  • the Total number of shells: 928
  • the Total number of narrow shells: 348
  • the Total number of round shells: 580

     Percent of Narrow Shell = 348/928 = 0.375 -->   0.375* 100 = 37.5%

     Percent of Round Shell = 580/928 = 0.625 -->   0.625*100= 62.5%

At the end

  • the Total number of shells: 800
  • the Total number of narrow shells: 564
  • the Total number of round shells: 236

     Percent of Narrow Shell = 564/800 = 0.705--> 0.705*100 = 70.5%

     Percent of Round Shell = 236/800 = 0.295-->  0.295*100 = 29.5%
