Answer:
Bernice would need 6 days assuming that everything remains constant to make $2430.
Step-by-step explanation:
Assuming she sells every single seashell every day.
First, find the total amount she makes per day by multiply the amount she sells them for ($3) with the total amount of sea shells she sells each day ($135):
135 x 3 = $405
Bernice makes $405 each day.
Now, to solve for the amount of days, divide the total amount she wants to make ($2430) with the amount she makes per day ($405):
2430/405 = 6
Bernice would need 6 days assuming that everything remains constant to make $2430.
