$1.$ Mathis owns a store that sells antique wooden toys, as well as custom$-$made toys. Bob approaches Mathis and indicates that he is very interested in an antique toy that Mathis has on display. The toy is extremely rare and, after a tense conversation, the parties agreed to a price of $$4,500.$ A month earlier, Mathis purchased the toy in question for $$3,000.$ Two days before the agreed to transaction date $($the toy was large and Bob would need to return with a pickup truck to hold the toy$),$ Bob repudiated the contract because he found the same antique toy for $$3,500$ elsewhere. Mathis sues Bob. How would Mathis$$s damages be computed under the following scenarios, which are independent of each other.

a$.$ Mathis resells the toy for $$4,000.$

b$.$ Mathis resells the toy for $$5,000.$

c$.$ Mathis chooses to keep the toy because he cannot find a buyer. At the agreed to transaction date, the toy$$s FMV was $$3,750.$
