The number of athletes that finished the race this year was 4284 athletes.
What is percentage?
10%, a comparative figure denoting one hundredth of any quantity. One percent, denoted by the symbol 1%, is equal to one hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified.
Let x represent the amount of athletes that finished the race this year.
Last year, 3,570 athletes finished the Silvergrove Marathon. This year, the number of runners crossing the finish line was 20% higher. Hence:
x = 3570 + 20% of (3570)
x = 3570 + (0.2 * 3570)
x = 4284
4284 athletes finished the race.

Answer:
y=-13/9x+27
Step-by-step explanation:
You should divide when converting a larger unit to a smaller unit.
Since the ratio of students with green eyes to students with blue eyes in the graph is 20/10, we can see that there is 1 blue eyed student for every green eyed student. Meaning that there will be half as many blue eyed students as green eyed students. So if there are 300 students we know that there will be 150 blue eyed students.
