Answer:
$340,000
Explanation:
Total costs for producing 150,000 units = $320,000
if fixed costs are $150,000, that means that the variables costs = $320,000 - $150,000 = $170,000
variable cost per unit = $170,000 / 150,000 units = $1.33 per unit
total variable costs for producing 300,000 units = 300,000 x $1.13 = $340,000
