Question

Erin and Jamie are collecting shells while the tide is out. Erin has 27 shells, and she has 9 more than Jamie. Write an equation for this situation and find how many shells Jamie has collected.

A) 27 = j + 9; Jamie collected 18 shells

B) 27 = j + 9; Jamie collected 36 shells

C) 27 + 9 = j; Jamie collected 36 shells

D) 27 = j – 9; Jamie collected 36 shells

Answer 1

The correct equation for this situation is: 27 = j + 9, where j represents the number of shells Jamie has collected.

To find out how many shells Jamie has collected, we need to solve this equation for j:

27 = j + 9

Subtracting 9 from both sides of the equation:

27 - 9 = j + 9 - 9

18 = j

Therefore, Jamie has collected 18 shells.

So, the correct answer is A) 27 = j + 9; Jamie collected 18 shells.
