Answer and Explanation:
The computation of the unused resource capacity in energy and repairs for Tri-State Mill. is shown below;
For energy
= $6,900 - 6,000 × $0.90
= $6,900 - $5,400
= $1,500
For repairs
= $12,000 - 600 × $16
= $12,000 - $9,600
= $2,400
Hence, the unused resource capacity in energy and repairs for Tri-State Mill. is $1,500 and $2,400 respectively
