Bernice sells 135 seashells by the seashore every day. she sells each sea shell for 3 dollars. for how many days does bernice need to sell seashells to earn 2430 dollars?

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.

~

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
