Answer:
$ 700,000
Explanation:
Data provided:
Total units sold = 100,000
cost per unit of wrench = $ 12 / unit
Fixed cost = $300,000
The net income for the company = $200,000
Now,
the total selling cost of the units sold = units sold × cost per unit
or
the total selling cost of the units sold = 100,000 × $ 12 = $ 1,200,000
also
Selling cost = Fixed cost + Variable cost + Net income
thus,
Variable cost = Selling cost - (Fixed cost + Net income)
on substituting the values, we have
Variable cost = $ 1,200,000 - ($300,000 + $200,000) = $ 700,000
