If 20 machines produce 1,240 printers in a day, how many more machines are needed to produce 1,984 printers in a day?
Correct answer: A. 12
- A. 12
- B. 20
- C. 24
- D. 32
Explanation
To determine how many more machines are needed, set up a proportion based on the given information. We know that 20 machines produce 1,240 printers in a day. To produce 1,984 printers, let x be the additional machines needed: 20 machines / 1,240 printers = (20 + x) machines / 1,984 printers Cross-multiply to solve for x: 20 * 1,984 = (20 + x) * 1,240 39,680 = 24,800 + 1,240x 14,880 = 1,240x x = 14,880 / 1,240 = 12 Therefore, 12 more machines are needed. Option A is correct. Options B, C, and D represent incorrect calculations or assumptions about the production increase required.
