Answer:
The cost 3 is 890000 dollars.
Explanation:
Total product costs = $2100000
Variable cost included in total product costs = $450000
Fixed cost included in total costs = $900,000
Mixed costs = $750000
[tex]\text{Variable cost per machine hour} = \frac{Varible costs}{Machine hours} \\[/tex]
[tex]= \frac{450000}{150000} \\[/tex]
[tex]= $3 dollar[/tex]
[tex]\text{Now to find mixed cost when there are 200000 machine hours that has costing 2390000 dollars.} \\[/tex][tex]total \ costs = 2390000 \ dollars \\[/tex]
[tex]variable \ cost \ (cost 1), \ 200000 \times 3 = 600000 \ dollars \\[/tex]
[tex]Fixed \ costs \ (cost 2) = 900000 \ dollars \\[/tex]
[tex]cost 3 (mixed cost) = Total costs - variable cost - Fixed costs[/tex]
cost 3 (mixed cost) = 2390000 – 600000 - 900000
cost 3 (mixed cost) = 890000 dollars.
