Difficulty: Easy
Correct Answer: None of these
Explanation:
Introduction / Context:We equate a known percent of a number to a simple product and solve for the unknown multiplicative factor. This is an algebraic one-step solve after computing the percent value.
Given Data / Assumptions:
Concept / Approach:Compute the left-hand side first. Then divide by 15 to isolate (?). Verify if the result is present among the options.
Step-by-Step Solution:
75% of 480 = 0.75 * 480 = 360.So (?) × 15 = 360 ⇒ (?) = 360 / 15 = 24.Verification / Alternative check:Check: 24 × 15 = 360, matching 75% of 480. Therefore, the correct value is 24.
Why Other Options Are Wrong:
Common Pitfalls:Stopping after computing 360 and selecting it as the answer. The question asks for the multiplier (?), not the percent result.
Final Answer:None of these
