Question
Saving money
It is desired to build a pipeline from an at-sea oil well at P to a refinery on
the shore at Q. Building a pipe costs 500, 000 dollars per mile under water
and 300,000 dollars per mile under land.
(This problem borrowed from here (example 5)).
The figure computes the cost for an adjustable set of points P, Q, and
(x,0).

Suppose the oil well is 2 miles offshore and the refinery is 3 miles along the
coastline.
(a) How much would the pipeline cost if the pipe went directly to shore (for
2 miles) and then along the shore for 3 miles? (If using scientific notation,
replace the e in the Julia output with E.)
(b) How much would the pipeline cost if the pipe went directly to the
refinery? (If using scientific notation, replace the e in the Julia output with
E.)
(c) What formula will describe the cost, where x, 0 <x < b, is the position
along the shore where the pipeline meets, a the distance out from shore,
and b the distance along the shore.
