Question

Aircraft Products, a manufacturer of aircraft landing gear, makes 2,100 units each year of a special valve used in assembling one of its products. The unit cost of producing this valve includes variable costs of $69 and fixed costs of $55. The valves could be purchased from an outside supplier at $76 each. If the valve were purchased from the outside supplier, 40% of the total fixed costs incurred in producing this valve could be eliminated. Buying the valves from the outside supplier instead of making them would cause the company's operating income to:

Answer 1

Answer:

Increase by $31,500

Explanation:

Calculation to determine the operating income

First step is to calculate the Total relevant cost

DIFFERENTIAL ANALYSIS

MAKE BUY

Variable cost $144,900 $0

(2,100*$69)

Fixed cost $46,200 $0

(2,100*55*40%)

Purchase cost $0 (2100*76) = $159,600

Total relevant cost $191,100 $159,600

Now let determine the Increase or decrease of the company's operating income

Increase by =($191,100- $159,600)

Increase by = $31,500

Therefore Buying the valves from the outside supplier instead of making them would cause the company's operating income to: Increase by $31,500
