The point where the two lines intersect is the solution to the system of linear equations, which is: A. (300, 108).
Given that:
y = total cost
x = miles
We are also given the system of linear equations that models the scenario given as:
y = 0.27x + 27 --> equation 1
y = 0.21x + 45 --> equation 2
To find the value of x, make both equations equal to each other and solve:
0.27x + 27 = 0.21x + 45
Combine like terms
0.27x - 0.21x = -27 + 45
0.06x = 18
Divide both sides by 0.06
0.06x/0.06 = 18/0.06
x = 300
To find the value of y, plug in the value of x into equation 1, and find y:
y = 0.27(300) + 27
y = 81 + 27
y = 108
Thus, the point where the two lines intersect is the solution to the system of linear equations, which is: A. (300, 108).
