I need help with finding the Basis with the below details.

Provide the calculations for Jon and Billy's basis in Bizrate's stock and Bizrate basis in the new assets it holds based on the information below:

Sold 500 shares of SBUX stock for $35,000 on December 1, 2018.The stock had been purchased by Jon on July 1, 2004 for $20,000 and was contributed by him on February 22, 2018, when it was worth $30,000.Also, on December 1, 2018 sold 100 shares of Grand View, Inc. for $2,000.The stock had been purchased on March 1, 2018 for $3,000.At no time did Bizrate own more than 1% of the outstanding stock of these corporations.

$2,500 is allocable to the investments in stock.The remainder is related to Bizrate's business.

Bizrate owns less than 20% of the outstanding stock of each of these corporations.
