-----------------------------------
cross%28y=8x%2B50%29
y=8%28x-30%29%2B50, x%3E30

y=50, 0%3Cx%3C=30
----------------------------------



x=82;
y=8%2A%2882-30%29%2B50
y=8%2852%29%2B50
y=416%2B50
y=466

Cost to drive 82 miles: highlight_green%28%22%24466%22%29

With x being amount of miles, correct piece-wise function: 

All other answers are INCORRECT, NONSENSICAL, and just PLAIN SILLY, so IGNORE!
