The cost of an electrode position control system in an electric arc furnace was $16,000 when the applicable equipment cost index had a value of 1192. If the current index value is 1364 and the exponent in the cost-capacity equation has a value of 0.65, the estimated cost now of a similar system twice as large is closest to: (choose one)
(a) $17,465
(b) $21,545
(c) $28,730
(d) $36,130
Costnow = 16,000 (1364/1192) (2)^0.65
= $28,729
Answer is (c) $28,730
