picking numbers c = 5 b = 2 200 paperclips per carton 200 * 5 = 1000 per case A. 1000 B. 200/5 = 40 C. 2000 D. 400/5 = 80 E. 20

To complete your answer, there are 2 cases so answer (C) is correct.

Bunuel has already demonstrated an algebraic approach, so let's try solving it by picking some numbers (aka using the INPUTOUTPUT approach). Let b = 3 and c = 5So, a case contains 5 cartons. Each carton contains 3 boxes, and each box contains 100 paper clips. So, the number of paper clips in 1 case = (100)( 5)( 3) = 1500 How many paper clips are contained in 2 cases?The number of paper clips in 2 cases = 3000So, we're looking for the answer choice so that when we INPUT b = 3 and c = 5, we get an OUTPUT of 3000Now check the answer choices: (A) 100( 3)( 5) = 1500 ELIMINATE (B) 100( 3)/( 5) = 60 ELIMINATE (C) 200( 3)( 5) = 3000 KEEP!! (D) 200( 3)/( 5) = 120 ELIMINATE (E) 200/( 3)( 5) = 200/15 ELIMINATE Answer: C RELATED RESOURCESAs you can see, Bunuel and I have demonstrated the two methods (Algebraic and InputOutput) for solving a question type I call Variables in the Answer Choices. If you'd like more information on these approaches, we have some free videos: Cheers, Brent

Each carton contains b boxes, and each box contains 100 paper clips. Thus we can say the following: c x b x 100 = 100bc paper clips per case. Thus, 2 cases would contain 2 x 100bc = 200bc paper clips. The answer is C.

I think you can draw this out (really helped me)
1 case > 2 cartons > 1 carton = 3 boxes > 1 box = 100 pc >> From here, there are 300 pc in 3 boxes (AKA 1 carton). Since you have 2 cartons here, in 1 case, you have 600 pc. >> You want 2 cases, so you have 1,200 pc.
Plug in A/C w/ variables you defined above: c=2 (cartons) b=3 (boxes)
When you plug in, should give you: 1,200.
C) 200bc > 200(3)(2) > 200(6) > 1,200
