Answer:

Commutative Property of Multiplication

Commutative Property of Multiplication is the switching of the order first factor  (multiplicand) and the second factor (multiplier), which does not change the product. For example, 4 × 5 = 5 × 4

-5 × 12 = -60

12 × -5 = -60

I need help with Estimated Variable and Fixed Cost. How do I figure that out in the problem attached?
saul85 [17]

The fixed and variable costs of the given table of production costs are respectively; $161280 and $42

<h3>How to calculate fixed and variable costs?</h3>

Variable costs are costs that vary/change depending on the company’s volume of production while fixed costs are costs that do not change in relation to volume of production.

Fixed costs = Production Cost + Selling expenses + Administrative Expenses

Fixed Cost = $103200 + $21500 + $7300 + $1600 + $1800 + $21000 + $2600 + $2280 = $161280

Variable cost = $15 + $10 + $8 + $3 + $3 + $1 + $2

Variable cost = $42
