This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.

What this question is testing

Objective: Number Sense

Prompt focus: A jacket originally priced at 80 dollars is on sale for 25 percent off. What is the sale price of the jacket?

Why the correct answer works

60 dollars

25 percent of 80 is 20, and 80 minus 20 equals 60 dollars.

Why the tempting wrong answer fails

65 dollars would result from a 15 dollar discount, which is incorrect.

Plain-language takeaway

A 25 percent discount removes one quarter of the price. One quarter of 80 dollars is 20 dollars, so subtracting 20 from 80 gives a sale price of 60 dollars.

Simple analogy

Think of number sense like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
