Answer:
280
Step-by-step explanation:
each individual line is a +20, therefore one line before 300 would be 300-20=280
Since there are 5 spaces between each multiple of 100, you know that each tick mark between them represents a multiple of 20. The marked number is the 4th tick mark, which means it is 200 + 4(20), or 280.
