PROBLEM
Grunar
Industries
produces
the
component
parts
needed
for
its
popular
non-commercial-use
drones.
One
of
the
key
parts
has
become
more
costly
to
produce
than
first
planned,
however,
so
management
is
considering
outsourcing
that
part.
If
the
company
decides
not
to
manufacture
this
part,
a
portion
of
its
fixed
manufacturing
overhead
costs
would
continue.
The
costs
to
produce
one
such
part
internally
and
to
purchase
on
part
from
the
suppler
are
given
here.
