You found a groupon for 25% off 4 tickets for christmas town, at busch gardens a ticket cost 54.65 each you and your three friends decided to go calculate the expense for the four tickets.

$163.95

Step-by-step explanation:

54.65 x 4 = 218.60

218.60 x (1-.25) = 163.95

i'm not sure i quite understand, could you provide more information?

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
