The budget for the Grant Center assumes a linear relationship between the number of student visitors and daily operating cost. Some sample (number of students, operating cost) values are given in the table.
A.Use the given data to write an equation showing how operating cost C, depends on number of students x.
B.How much does the daily operating cost increase due to a single student visitor?
C.What is the y-intercept of this line and what does it mean in regards to the cost situation at the Grant Center?

Step-by-step explanation:
The Grant Center for Outdoor Education gives student groups experience in studying nature and
helping to restore the environment for fish, birds, and animals.
1. The number of seeding trees that can be planted in one day depends on the number of students in the
work group. Data from several different work groups is shown in the next graph.
a. Draw a line that estimates the pattern in (workers, trees) data.
b. Write an equation for your graph model relating trees planted to number of workers.
c. Use your linear model to estimate how many trees will be planted by a work crew of 10.
Show how you find your answer.
d. Use your linear model to estimate how many workers will be required to plant 310 trees.
Show how you find your answer.
e. What is the slope of your linear model? What does that slope tell about the relationship
between the variables
