You would do for pens
22 x 1.15 =25.30
And for markets
15 x 2.05 = 30.75

You are moving in the path of a parabola.
The conic section is parabolic - the street is the directrix and the mailbox is the focus.
2(2^4) - 5(2^2) - 3*2 + 2 = 32-20-6+2 = 8
Fine the length BC using the cosine law. Google the law and sub it in
