Finish Question $2$ by more details and clearly.

Kaplan prepares financial statements to $30$ September each year. Notes $1$ and $2$ provide information on revenue transactions relevant to the year ended $30$ September $2023.$

Note $1-$ Sale of product with right of return

On $1$ April $2023$ Kaplan sold a product to a customer for $$121,000.$ This amount is payable on $30$ June $2025.$ The manufacturing cost of the product for Kaplan was $$80,000.$ The customer had a right to return the product for a full refund at any time up to and including $30$ June $2023.$ At $1$ April $2023,$ Kaplan had no reliable evidence regarding the likelihood of the return of the product by the customer. The product was not returned by the customer before $30$ June $2023$ and so the right of return for the customer expired. On both $1$ April $2023$ and $30$ June $2023,$ the cash selling price of the product was $$100,000.$ A relevant annual rate to use in any discounting calculations is $10\%.$

Note $2-$Sale with a volume discount incentive

On $1$ January $2022$ Kaplan began an arrangement to sell goods to a third party $-$ entity B$.$ The price of the goods was set at $$100$ per unit for all sales in the two$-$year period ending $31$ December $2023.$ However, if sales of the product to entity B exceed $60,000$ units in the two$-$year period ending $31$ December $2023,$ then the selling price of all units is retrospectively set at $$90$ per item.

Sales of the goods to entity B in the nine$-$month period ending on $30$ September $2013$ totalled $20,000$ units and this volume of sales per month was not expected to change before $31$ December $2023.$

However, in the year ended $30$ September $2023,$ total sales of the goods to entity B were $35,000$ and based on current orders from entity B$,$ the estimate was revised. The directors of Kaplan estimated that the total sales of the goods to entity B in the two$-$year period ending $31$ December $2023$ would be more than $60,000$ units.
