Given that
The grocery store has 27 cases and needs some more to complete the display.
And we have to find the remaining number of cases.
Explanation -
Let the number of cases required is x.
Now, the grocery store has 27 cases and it needs 50 cases to complete the display.
Then,
It means that the store requires a total of 50 cases.
And this situation can be written as
x + 27 = 50
x = 50 - 27
x = 23
So the cases required will be 23.
Final answer - Therefore the final answer is 23.
