7. Nadir bought a new home theatre system with 7.1 surround sound, 3D TV, and leather theatre seating for $10,000 from Best Future Electronics on March 20. He paid $2000 in cash and signed a conditional sale contract requiring a payment on July 1 of $3000 plus interest on the $3000 at a rate of 11%, and another payment on September 1 of $5000 plus interest at 11% from the date of the sale. The vendor immediately sold the contract to a finance company, which discounted the payments at its required rate of return of 16%. What proceeds did Best Future receive from the sale of the contract?
