Answer:
$0.215
Explanation:
The computation of the cost per item in Group 1 is shown below:-
Candy amount paid = $3,100
Item received = 7,100
For Group 1
Sale value = Group 1 units × Selling price
= 2,110 × $0.15
= $316.5
For Group 2
Sale value = Group 2 units × Selling price
= 4,720 × $0.35
= $1,652
For Group 3
Sale value = Group 3 units × Selling price
= 270 × $0.71
= $191.7
= Total sale value = $316.5 + $1,652 + $191.7
= $2,160.2
So, Sale percentage for Group 1 = $316.5 ÷ $2,160.2
= 14.65%
Now, the proportion of cost for Group 1
= $3,100 × 14.65%
= 454.15
Cost per unit = Proportion cost ÷ Group 1 units
= $454.15 ÷ 2,110
= $0.215
