To find the original price of each apple, let's denote the original price per apple as \( x \).
When Eve buys 4 apples, she gets a discount of 25 cents per apple. So, the price per apple when she buys 4 is \( (x - 0.25) \).
Given that Eve bought 12 apples total for $15, we can express that situation in an equation:
\[ 12(x - 0.25) = 15 \]
Thus, the correct equation to represent the problem algebraically is:
12(x − 0.25) = 15
