Hello, I have to create my own question. Is this correct? If not, how should I fix it?

VaultTech makes high-end security vaults. The regular price is $8,600 per vault. A jewelry store wants to buy 9 vaults at a discounted price of $6,000. This is a one-time deal (i.e., a short-term decision), and VaulthTech has enough spare capacity. How would the special-order affect VaultTech's operating income? Should VaultTech take the special order? VaultTech makes high-end security vaults. The regular price is $8,600 per vault. A jewelry store wants to buy 9 vaults at a discounted price of $6,000.
