Answer:
Option (b) is correct.
Step-by-step explanation:
Given that,
factory utility cost:
$3,636 for 650 cases bottled, and
$3,724 for 900 cases bottled.
Variable factory utility cost:
= Change in cost ÷ change in units
= (3,724 - 3,636) ÷ (900 - 650)
= 88 ÷ 250
= $0.352
Therefore, the variable factory utility cost per case bottled is closest to $0.352.
