Solution: Total number of pages = 300

=> Revised once: 80

=> Revised twice: 50

=> Remaining: 300 – (80 + 50) = 170

=> Rate for first typing: $10

=> Rate for first revised: $5

=> Rate for second revised: $5 + $5 = $10

=> Total cost = (170 * 10) + (80 * 5) + (50 * 8) = 1700 + 400 + 400 = $2,500

Therefore, D is the correct answer.

Answer D
