To solve this problem, let's use some numbers to help us compare.
Say each tire costs $100.
Deal 1: Buy 3, get 1 free
Total = $300
Ratio = 3:4
---To find the ratio, we'll take the deal price and compare it to the original price ($400)
Deal 2: 1/4 off the total price
1/4 of 400 = 100
400 - 100 = 300
Total = $300
Ratio = 3:4
Therefore, the deals are equivalent.
Correct Answer: D
