Answer:
$10,458.30 
Step-by-step explanation:
For computing the cost of new piece first we have to find out the capacity of 1,000 units which is shown below:
Cost of equipment having capacity of 1000 units 
= (New equipment capacity ÷ original capacity equipment)^power-sizing exponent for this type of equipment × past purchase
= (1000 ÷ 2000)^0.28 × $10,000
= $8,235.91 
Now
Cost of new equipment today is 
= Cost of new equipment × (Current cost index ÷ Old cost index) 
 = $8,235 × (160 ÷ 126) 
= $10,458.30
