Cullumber Ltd. sells goods to Culmer Corporation during the calendar year ending December 31, 2023. Culmer is a key customer to Cullumber and a volume discount scheme has been established to strengthen the relationship further. The volume discount scheme is as follows: for sales for the year of 4,130 units, a discount of 2% is granted; for sales for the year reaching 5,290 units, a discount of 4% will be granted; and, finally, if sales for the year reach 8,220 units, a discount of 5% will be granted. For the first half of the year, Cullumber sold to Culmer, on account, 3,650 units at a sales price of $135,050. Because the second half of the year is slower for sales, it has been Cullumber's experience that sales to Culmer for the year will be 6,280 units.
