Answer:
 The inspecting costs should be allocated to the Basic model using ABC costing is $30,600
Step-by-step explanation:
The computation of the inspecting cost is shown below:
= Total number of basic model inspection + the total number of inspection
where, 
Total number of basic model inspection equals to
= Number of units produced ÷ every units produced
= 3,400 units ÷ 100 
= $34
And, the total number of inspection equals to
= Total inspection cost ÷ number of inspection
= $84,600 ÷ $94
= 900 
The number of inspection includes
= total number of basic model inspection + the total number of luxury model inspection 
= $34 + $60 (600 units ÷ 10)
Now put these values to the above formula 
So, the value would equal to
= 900 × $34
= $30,600
