Answer:
the variable cost of production (per month) is $21,000
Step-by-step explanation:
The computation is shown below:
The variable cost per month is
= Number of pizza produced per month × (labor per pizza + in ingredients per pizza + in electricity per pizza )
= 5,000 × ($3.00 + $1.00 + $0.20)
= 5,000 × $4.20
= $21,000
Hence, the variable cost of production (per month) is $21,000
