March 2026 SAT Percent Problems Explained: What This Question Tests
This example is useful for practicing March 2026 SAT Percent Problems Explained because it shows how a student must connect the wording of the sentence to the logic of the answer choices. Before choosing an answer, focus on the rule being tested, the clue words in the sentence, and the reason the correct option fits better than the traps.
This question tests your ability to calculate percentage discounts correctly. Many students make the same critical error—they calculate the discounted price instead of the discount amount.
📚 The Rule: Understanding Reading & Writing
There are two distinct calculations in discount problems: (1) finding the discount amount (the money saved), and (2) finding the discounted price (the amount paid after the discount). These are different numbers. The discount amount equals the original price multiplied by the discount percentage (as a decimal). The discounted price equals the original price minus the discount amount.
The most common mistake occurs when students confuse these two calculations. They calculate the discounted price but the question asks for the discount amount, or vice versa. You must read the question stem carefully every time to determine which calculation is required.
How to Attack These Questions:
- Step 1: Identify what the question is actually asking for. Read the final sentence carefully: 'How much less is the discounted cost than the regular cost?' This asks for the difference between the two prices, which is the discount amount.
- Step 2: Calculate the discount amount using the standard formula: Original Price × Discount Percentage = Discount Amount. Convert 25% to 0.25 and multiply: $312 × 0.25 = $78.
- Step 3: Eliminate answers that represent other calculations. $312 is the original price. $234 is the discounted price ($312 - $78). $25 is simply the percentage number without proper calculation.
Passage Context: A 'discount' is a reduction in price. 'Annual' means yearly. The context involves basic consumer math that appears frequently in test questions about real-world scenarios.

✅ The Correct Answer
The correct answer is $78 because this represents the actual discount amount. The question asks 'how much less' the discounted cost is than the regular cost. This difference equals the discount itself. Following the standard percentage formula: Regular cost ($312) × Discount percentage (25% = 0.25) = $78. This is the money saved, which answers the question precisely.

Choice C: This choice represents the discounted price ($312 - $78 = $234), not the discount amount. It answers a different question: 'What is the discounted cost?'
🩺 Diagnosis: Practice distinguishing between 'discount amount' and 'discounted price'—these are different calculations.
Choice D: This choice is the original price, not any calculation involving the discount. It shows a complete misreading of the question.
🩺 Diagnosis: Work on careful reading—you selected the number given in the problem without performing any calculation.
⚠️ Anatomy of the Trap
The Global Trap: Test-makers include answers that represent common calculation errors or answers to different questions. They know students often calculate the discounted price when asked for the discount, or use the percentage number as the answer.
In this exact question: In this question, $234 is the discounted price, which many students will calculate. The test-makers include it knowing students will stop there without checking what the question actually asks for.
