The Johnny Ho Manufacturing Company in? Columbus, Ohio, is putting out four new electronic components. Each of? Ho's four plants has the capacity to add one more product to its current line of electronic parts. The? unit-manufacturing costs for producing the different parts at the four plants are shown in the accompanying table:

PLANT

Component	1	2	3	4
C53	0.13	0.09	0.16	0.14
C81	0.07	0.03	0.04	0.05
D5	0.30	0.44	0.36	0.34
D44	0.18	0.15	0.16	0.17

The optimal assignment of plants to components that minimizes the cost is:

Plant 1? (choose one of the following: C53, C81, D5, D44)

Plant 2? (choose one of the following: C53, C81, D5, D44)

Plant 3? ? (choose one of the following: C53, C81, D5, D44)

Plant 4? ? (choose one of the following: C53, C81, D5, D44)

The cumulative cost of the optimal assignment of plants to components = ____ dollars (round response to two decimal places)
