Answer:
selling and administrative cost formula:
Y = $166,200 + $6.80X
Explanation:
First we solve for the units sold during hte period:
sales: 960,000
unit selling price: 60
units sold: 960,000 / 60 = 16,000
Then we calcualte the variable cost of both, selling and administrative:
selling variable 8% of selling 8% of $60 = 4.8
administrative $ 2
total variable: 6.8
Now we solve for fixed cost:
275,000 = 6.8 (16,000) + fixed
fixed = 275,000 - 108,800 = 166,200
