Troy Inc. was approached by an outside vendor willing to pre$-$treat outdoor fabric for them $($that they currently do themselves$)$ for $$3\mathrm{.}15$ per yard. The cost per unit to treat fabric last year was:

Direct material $$1\mathrm{.}14$

Direct labor $$\mathrm{.}30$

Variable manufacturing overhead $$\mathrm{.}20$

Variable selling and administrative $$\mathrm{.}52$

Fixed manufacturing overhead, traceable $$1\mathrm{.}10$ at $2,000$ yard volume

Allocated fixed manufacturing overhead $$2\mathrm{.}50$ at $2,000$ yard volume

They expect to need $2,000$ yard of fabric treated this year. If they decide to outsource, they will close out the treating process completely. What is the financial advantage $($disadvantage$)$ of outsourcing this process to the vendor to treat the fabric? Report as a whole number with disadvantage as a negative.
