Correct answer: C
Answer: 1440 copies on the faster copier.
Step-by-step solution:
Let x be the number of copies the slower copier makes in the time both finish.
The faster copier runs at 150% of the slower copier, so it makes 1.5 × x copies in the same time.
Total copies: x + 1.5x = 2400 → 2.5x = 2400 → x = 960.
Copies by the faster copier: 1.5 × 960 = 1440.
Therefore, the faster copier should make 1440 copies so both finish at the same time.
