Answer:
6 be the number of days Bernice need to sell sea shells to earn 2430 dollars .
Step-by-step 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 = 6
Therefore the 6 be the number of days Bernice need to sell sea shells to earn 2430 dollars .
