Answer: d. 25
Step-by-step explanation: This is correct because the graph starts at 75 and then jumps to 100. 75 + 25 is 100. This then goes from 100 to 125. Again, 100 + 25 is 125. Finally, it goes from 125 to 150. 125 + 25 equals 150. The final answer is 25 because each time the line increases, it increases by 25.
