Answer 2

6 be the number of days Bernice need to sell sea shells to earn 2430 dollars .

Explanation:

As given

Bernice sells 135 sea shells by the sea shore every day.

She sells each sea shell for 3 dollars.

Total amount of money Bernice earns by selling sea shells in a day = Total number of sea shells sell in a day × Cost of each sea shell

Putting the values in the above

Total amount of money Bernice earns by selling sea shells in a day = 135 × 3

Total amount of money Bernice earns by selling sea shells in a day = $405

As given

Bernice need to sell sea shells to earn 2430 dollars.

Let us assume that the number of days Bernice need to sell sea shells to earn 2430 dollars be x.

Than the equation becomes

405 × x = 2430

405x = 2430

`x = (2430)/(405)`

x = 6

Therefore the 6 be the number of days Bernice need to sell sea shells to earn 2430 dollars .
