Bernice sells 135 sea shells by the sea shore every day. she shells each sea shel for 3 dollars. for how many days does bernice need to sell sea shells to earn 2430 dollars

First we want to calculate exactly how much money Bernice sells on a daily basis, so we can determine how many days it'll take to earn 2,430 dollars. We can do this by multiplying the amount of shells she sells every day by the amount she sells them for. So 135 sea shells multiplied by 3 dollars.

135 * 3

This comes up to 405 dollars every day, quite a significant amount considering she's selling shells. Now, divide 2,430 dollars by 405 dollars. This will give us the final result.

2,430 / 405

It will take Bernice exactly 6 days to earn 2,430 dollars.
