C1=39.95,
C2=19.95+0.49m
19.95+0.49m=39.95
0.49m=20
m≈40.82
At any point where the mileage is greater than 40.82 mi, C1 will be less than C2.

The quadratic equation that has a vertex at (4,-3) and passes through (6,-1) is given by:
y = 0.5(x - 4)² - 3.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the vertex is at (4,-3), hence:
h = 4, k = -3.
The equation is:
y = a(x - 4)² - 3.
When x = 6, y = -1, hence we use it to find the leading coefficient a as follows:
-1 = a(6 - 4)² - 3
4a = 2.
a = 0.5.
Hence the equation is:
y = 0.5(x - 4)² - 3.
