Answer:
The answer is 3,906.25
Step-by-step explanation:
All you have to do is divide 15,625 by 4! :)
Undefined means it goes through the x intercept, x=3
To solve this problem you have to set up a proportion. To form one side of the proportion you use "is over of" meaning what number represented by is, in this case 18, is placed over the number represented by of, 3000.

Since you are finding the percent of something, youre x value is placed above "100" because percent values are most commonly out of 100%.
So now your proportion will look like


To solve the proportion you cross multiply and divide. So you multiply 100 and 18 since they are crossed from each other, then divide 1800 by 3000. The answer is .6. 18 is .6% of 3000.
Since 800 is greater than 0.8 your statement would be 800>0.8
