Weldon bought a pair of hiking boots that cost $58.50 before tax. If an 8.5% tax is added to Weldon's total, how much did he spend in total on the hiking boots?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
