A company is offering to pay a stadium for naming rights. If the administrative costs for this sponsorship are $78,000, and thes
marusya05 [3725]

Answer:

The company’s offer for the rights to name the stadium amounts to $71,760.

Explanation:

The sponsorship’s total administrative cost is $78,000, which constitutes 8% of the revenue generated from the naming rights. Hence,

= Revenue × Percentage

= $78,000 × 8%

= $6,240

To find the amount proposed for the naming rights, we subtract the revenue-related expense from the total cost:

= $78,000 - $6,240

= $71,760

Answer:

  1. a. $950,000.
  2. $150,000.
  3. a. $1,115,000.
  4. d. -$15,000.
  5. b. the difference between what a person currently makes and what they would earn in their best alternative.

Explanation:

1. Chris's accounting costs

The accounting cost reflects the explicit expenses of the venture. They are the usual costs;

= Parts and materials needed for restoration + Salaries of employees + His salary + Rent along with utilities

= 400,000 + 360,000 + 110,000 + 80,000

= $‭950,000‬

2. Chris's accounting profits

= Revenue - Accounting cost

= 1,100,000 - 950,000

= $150,000

3. Chris's economic cost

These consist of explicit costs plus implicit (opportunity) costs.

The opportunity cost represents the next best option which amounts to $275,000 should he have taken the position with Jay Leno as a personal auto restorer.

This means forgoing the $110,000 he makes currently.

= Accounting cost + Foregone salary - Current salary

= 950,000 + 275,000  - 110,000

= $1,115,000

4. Chris's economic profit

= 1,100,000 - 1,115,000

= -$15,000

5. b. the difference between what a person currently makes and what they would earn in their best alternative.

Claremore Industries uses a weighted-average process-costing system. All materials are added at the beginning of the process; co
arsen [3447]

Answer:

$78,000

Explanation:

For calculating the cost of the ending work in process

To begin, we will calculate the material cost per unit.

Material cost per unit = $220,000 / (40,000+15,000)

Material cost per unit= $220,000 / 55,000

Material cost per unit= $4

Next is to find the conversion cost per unit

Conversion cost per unit= $414,000 / (40,000 + (15,000*40%)

Conversion cost per unit= $414000 / 46000

Conversion cost per unit= $9

Now, it’s time to calculate the total cost per equivalent unit

Total cost per equivalent unit= $4 + $9

Total cost per equivalent unit= $13

Then, the equivalent unit of the ending work in process

Equivalent unit of the ending work in process= 15,000 × 40%

Equivalent unit of the ending work in process= 6,000

Finally, we calculate the cost of the ending work in process

Cost of the ending work in process = 6,000 × $13

Cost of the ending work in process = $78,000

Thus, the cost of the ending work in process is $78,000
