The X Company stocks a variety of parts and materials it uses in its manufacturing processes. Recently, as demand for its finished goods has increased, management has had difficulty managing parts inventory; they frequently run out of some crucial parts and seem to have an endless supply of others. In an effort to control inventory more effectively, they would like to classify their inventory of parts according to the ABC approach. Following is a list of selected parts and the annual usage and unit value for each:

Item number	Annual usage (items/year)	Unit cost ($)	Item number	Annual usage (items/year)	Unit cost ($)
1	36	350	16	60	$ 610
2	150	30	17	120	20
3	50	23	18	270	15
4	300	45	19	45	50
5	18	1,900	20	19	3,200
6	500	8	21	910	3
7	710	4	22	12	4,750
8	80	26	23	30	2,710
9	344	28	24	24	1,800
10	67	440	25	870	105
11	510	2	26	244	30
12	682	35	27	750	15
13	95	50	28	45	110
14	10	3	29	46	160
15	820	1	30	165	25
