15-13 = 2
2+15 = 17
so 17 is your answer
1.5/75 = 0.02
0.02 x 100 = $2
Therefore the original price was $2.
The function is equal to (x+2) / (x+2)(x-2), so when you simplify, it would be 1/(x-2). This means that there is a hole in the graph at x=-2, and a vertical asymptote at x=2.
Answer: the total is 62.55 so you would be paying $2.55 in tax
