Question: 304

4. There were 6 pairs of earrings sold at a price of y dollars each. In terms of y, what is the total amount of money for which these earrings were sold?

  • A. 6 + y
  • B. 6y
  • C. 6y
  • D. 6 + 6y

Correct Answer: B

Explanation:

B This is a Plugging In question because there are variables in the choices and the question stem contains the phrase in terms of. Plug In a value, work through the problem to find a target answer, and then check each of the choices to see which yields the target answer. For instance, say that y = 10 pairs of earrings. The total amount of money for 6 pairs of earrings would be 6 × 10 = 60, which is the target answer. Now, plug 10 into the choices for y to see which choice matches your target answer (60). Eliminate (A) because 6 + 10 = 16, which does not equal 60. Keep (B) because 6(10) = 60. Remember to check the remaining choices when Plugging In. 610 is a very large number, much greater than 60, so eliminate (C). Eliminate (D) as well because 6 + 6(10) = 66, which does not equal 60. The correct answer is (B).
