The number of trays she needs is 94 trays.

Step-by-step explanation:

  • Total seashells = 762.
  • Number of trays she already has = 2 trays.
  • Number of seashells in each tray = 8 seashells.  

Number of trays she needs :

  • Number of seashells already arranged = 2[tex]\times[/tex]8 = 16 seashells.
  • Remaining seashells = 762 - 16 = 746 seashells.

Number of trays needed = Remaining seashells / 8

⇒ 746/8

⇒ 93 trays and remaining 2 seashells is arranged in another tray

⇒ 93+1 = 94 trays.
