Final answer:
To solve this problem, set up the equation (600 + 40)x = 2400, where x represents the number of days it will take Leilah to study all her flashcards.
Step-by-step explanation:
The given situation is: Leilah has not yet studied 600 of her 2400 flashcards and she studies 40 new cards each day. To match this situation, we can set up the equation (600 + 40)x = 2400, where x represents the number of days it will take Leilah to study all her flashcards. The equation accounts for the 600 cards she hasn't studied yet and the 40 new cards she studies each day. By solving the equation, we can find the value of x, which represents the number of days Leilah will need to study her flashcards.
