To find the original price of each apple (let's call it \( x \)), we need to consider that Eve bought 12 apples, and she received a discount of 25 cents per apple when she bought 4 or more.
Since she received a $0.25 discount per apple, the effective price she paid per apple is \( x - 0.25 \).
The equation to represent the total cost of the 12 apples would be:
\[ 12(x - 0.25) = 15 \]
So, the correct response from your options is:
12(x−0.25)=15
