Mark spends a total of $68.82 for 2 pairs of sneakers with the same cost. the sales tax is $5.32. mark also uses a coupon for $3.00 of his purchase. how much did each pair of sneakers cost?

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.
