Math Question: Dependent and Independent Variables:

Question

A miniature gold course has a special group rate. You can pay $20 plus 3$ per person when you have a group of 5 or more friends. Let f be the number of friends and c be the total cost. Determine which variable is independent and which is dependent and write an equation that models the situation then make a table that shows the cost for 5 to 12 friends. Plot the coordinate pairs on a graph. Make sure you label you're graph.

Answer 1

c = 20 + 3f,,, f is the independent variable and c is the dependent variable.

f I c

I

5 I 35

6 i 38

7 i 41

8 i 44

9 i 47

10 I 50

11 I 53

12 I 56

The graph is a straight line with y-intercept = 20 and slope = 3 Sorry this software doesn't allow me to graph.
