This is your first year of operations. You offer to your customers the following incentive program: for every $100 spent, they earn 10 points for every 200 points they can redeem a prize that costs you $30 and has a retail price of $45. You estimate that 60% of the total points earned by your customers will be redeemed. This year, your total sales amount to $3,500,000 and a total of 800 prizes were redeemed. You apply IFRS. Determine the ending balance of your deferred revenue-incentive program' account. (4 marks)
