Angel Fish Supplies is run in partnership by Angelina and her brother Arkady. The business supplies fish tanks and related goods to pet shops. Although the customers almost always eventually pay, the partners often have problems in collecting the cash due to them. The pattern of cash payment by customers, on average, is as follows. Month following sale 2 months following sale 3 months following sale 4 months following sale 30% of sales value 40% of sales value 20% of sales value 10% of sales value So, for example, 30% of the value of sales in February will actually be received in cash in March, 40% will be received in cash in April, and so on. Angelina and Arkady are preparing budgets for the six months ending 30 June 20X7. Actual invoiced sales for the September - December 20X6 period are as follows. September October November December 22,500 20,650 21,040 21,200 The partners expect to invoice sales as follows in each of the six months to 30 June 20X7. January February March April 18,400 18,000 19,600 20,400 22,600 23,100 May June By contrast with the slow receipt of cash for sales, Angelina and Arkady's suppliers expect to be paid immediately. Other expenses are also paid in the month in which they are incurred. So, there is no delay in paying for any goods or services by the partners.
