-15 degrees = -15 pi / 180 = -pi/12 radians
convert 7pi/6 to degrees
= 7pi/6 * 180 /pi = 210 degrees which is in Quadrant III
Because the magnetic forces move the poles.<span> </span>
Let x = number of miles, cost per mile = 82 cents = $0.82
Cost = 19.95 + 0.82*x
178.21 = 19.95 + 0.82x
0.82x + 19.95 = 178.21
0.82x = 178.21 - 19.95
0.82x = 158.26
x = 158.26/0.82
x = 193
