Answer:
The equation shows the relationship between the number of bags, b, and the total cost, c, for flying with this airline is:
C = 20b + 150
Hence, option C is correct.
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the rate of change or slope
- c is the y-intercept
Given that an airline charges $150 for a ticket. It means the initial condition is $150.
Therefore, the y-intercept c = 150.
Given that an airline charges $20 for each bag. It means the rate of change is $20 for each bag.
Therefore, the rate of change or slope m = 20
Let 'C' be the total cost and 'b' be the number of bags.
Thus, substituting y = C, x = b, m = 20 and c = 150
y = mx + c
C = 20b + 150
Therefore, the equation shows the relationship between the number of bags, b, and the total cost, c, for flying with this airline is:
C = 20b + 150
Hence, option C is correct.
