For how many days does Bernice need to sell sea shells to earn 2430 dollars?

Question

Bernice sells 135sea shells by the sea shore every day. She sells each sea shell for 3 dollars.

Answer 1

Let d = number of days

 

She sells 135 each day, at $3 per shell.  That nets her 135(3), or $405 per day.

 

To determine the number of days to earn $2430, we divide by $405.

 

2430/405 = 6

 

Thus, it will take 6 days to earn $2430.
