To find the original price per apple, let's break down the problem:
- Let \( x \) be the original price per apple.
- When Eve buys 4 apples, she gets a $0.25 discount per apple. Therefore, the price per apple when she buys 4 is \( x - 0.25 \).
- Since she bought 12 apples, for the first 4 she would pay: \[ 4(x - 0.25) \] and for the remaining 8 apples, she would pay the full price: \[ 8x \]
- The total cost for 12 apples can be expressed by combining these two parts. So, the total cost equation will be: \[ 4(x - 0.25) + 8x = 15 \]
Now let's simplify the total cost:
- Expanding \( 4(x - 0.25) \): \[ 4x - 1 \]
- Therefore the equation becomes: \[ 4x - 1 + 8x = 15 \] which simplifies to: \[ 12x - 1 = 15 \]
So, among the provided options, the equation that correctly represents the original scenario is not listed, and we should solve for \( x \) using \( 12(x - 0.25) = 15 \) or \( 12(x - 0.25) + 8x = 15 \) if it went with a total price but \( 12(x + 0.25) \) is wrong.
However, if we simplify from those equations:
- The closest to this would be \( 12(× - 0.25) = 15 \) since you're paying \( (x-0.25) \).
Thus, the correct equation to solve for the original price per apple based on the given options would be: \[ \text{Select } 12(× - 0.25) = 15. \]
Nonetheless, ensure to calculate as per the definitions above accordingly!
