a)

Summary Introduction

To determine: The break-even point of each oven given.

Introduction:

Break-even point (BEP):

The break-even point is measured in units or in sales term to identify the point in a business which is required to cover the total investment costs. The total profit at break-even point is zero.

Answer to Problem 20P

The break-even point of oven type A is 1,667 pizzas. The break-even point of oven type B is 2,353 pizzas.

Explanation of Solution

Given information:

Oven type A:

Number of pizzas = 20 / hour

Fixed cost = $20,000

Variable cost = $2.00 / pizza

Selling price= $14.00/ pizza

Oven type B:

Number of pizzas = 40 / hour

Fixed cost = $30,000

Variable cost = $1.25 / pizza

Selling price = $14.00 / pizza

Formula to calculate Break-even point (BEP):

BEP=Fixed costSelling priceVariable cost

Calculation of Break-even point (BEP) of oven type A:

The break-even cost of an oven is calculated by finding out the number of pizzas that an oven can cook.

The break-even point is calculated by dividing the fixed cost with the difference of selling price and variable cost.

BEPA=$20,000$14$2.00=$20,000$12=1666.67or1,667 pizzas

Hence, the Break-even point (BEP) for oven type A is 1,667 pizzas.

Calculation of Break-even point (BEP) of oven type B:

The Break-even point is calculated by dividing the fixed cost with the difference of selling price and variable cost.

BEPB=$30,000$14$1.25=$30,000$12.75=$2,352.94 or 2,353 pizzas

Hence, the Break-even point (BEP) for oven type B is 2,353 pizzas.

Answer to Problem 20P

The oven that needs to be purchased if the owner is expecting to sell 9,000 pizzas is oven type A.

Explanation of Solution

Given information:

Oven type A:

Number of pizzas = 20 / hour

Fixed cost = $20,000

Variable cost = $2.00 / pizza

Selling price = $14.00 / pizza

Oven type B:

Number of pizzas = 40 / hour

Fixed cost = $30,000

Variable cost = $1.25 / pizza

Selling price = $14.00 / pizza

Formula to calculate Profit:

Profit=(Number of selling pizzas×Selling price)(Number of selling pizzas×Variable cost)Fixed cost

Calculation of profit for oven type A:

The profit is calculated by multiplying number of selling pizzas with selling price and the resultant value is subtracted from the fixed cost and the value obtained by multiplying number of selling pizzas and variable cost.

Profit=(9,000×14.00)(9,000×2.00)20,000=126,00018,00020,000=88,000

The profit for oven type A is $88,000.

Calculation of profit for oven type B:

The profit is calculated by multiplying number of selling pizzas with selling price and the resultant value is subtracted from the fixed cost and the value obtained by multiplying number of selling pizzas and variable cost.

Profit=($9,000×$14.00)($9,000×$1.25)$30,000=$126,000$11,250$30,000=$84,750

The profit for oven type B is $84,750.

The profit of oven type A is more than oven type B. (88,000 > 84,750)

Hence, the owner must purchase type A oven.

c)

Summary Introduction

To determine: The oven that need to be purchased if the owner is expecting to sell 12,000 pizzas.

Answer to Problem 20P

The oven that needs to be purchased if the owner is expecting to sell 12,000 pizzas is oven type A.

Explanation of Solution

Given information:

Oven type A:

Number of pizzas = 20 / hour

Fixed cost = $20,000

Variable cost = $2.00 / pizza

Selling price = $14.00 / pizza

Oven type B:

Number of pizzas = 40 / hour

Fixed cost = $30,000

Variable cost = $1.25 / pizza

Selling price = $14.00 / pizza

Formula to calculate Profit:

Profit=(Number of selling pizzas×Selling price)(Number of selling pizzas×Variable cost)Fixed cost

Calculation profit for oven type A:

The profit is calculated by multiplying number of selling pizzas with selling price and the resultant value is subtracted from the fixed cost and the value obtained by multiplying number of selling pizzas and variable cost.

Profit=($12,000×$14.00)($12,000×$2.00)$20,000=$168,000$24,000$20,000=$124,000

The profit for oven type A is $124,000.

Calculation profit for oven type B:

The profit is calculated by multiplying number of selling pizzas with selling price and the resultant value is subtracted from the fixed cost and the value obtained by multiplying number of selling pizzas and variable cost.

Profit=($12,000×$14.00)($12,000×$1.25)$30,000=$168,000$15,000$30,000=$123,000

The profit for oven type B is $123,000.

The profit of oven type A is more than oven type B. (124,000 > 123,000)

Hence, the owner must purchase type A oven.

Answer to Problem 20P

The volume of pizzas at which JE person must switch the type of ovens is 13, 333 pizzas.

Explanation of Solution

Given information:

Oven type A:

Number of pizzas = 20 / hour

Fixed cost = $20,000

Variable cost = $2.00 / pizza

Selling price = $14.00 / pizza

Oven type B:

Number of pizzas = 40 / hour

Fixed cost = $30,000

Variable cost = $1.25 / pizza

Selling price = $14.00 / pizza

Let FA be the fixed cost for oven type A.Let VA be the variable cost for oven type A.Let FB be the fixed cost for oven type B.

Let VB be the variable cost for oven type BLet x be the volume of pizzas.

Formation of equation 1 for oven type A:

FA+(VA×x) (1)

Formation of equation 2 for oven type B:

FB+(VB×x) (2)

Calculation of volume of pizzas:

The volume of pizzas is calculated by substituting all the known values in equation (1) and (2) and equating each other.

FA+(VA×x)=FB+(VB×x)$20,000+($2.00×x)=$30,000+(1.25×x)$20,000+2x=$30,000+1.25x2x1.25x=$30,000$20,000

0.75x=$10,000x=$10,0000.75=13,333.33 or 13,333 pizzas

Hence, the volume of pizzas at which JE person must switch the type of ovens is 13, 333 pizzas.

Spartan Castings must implement a manufacturing process that reduces the amount of particulates emitted into the atmosphere. Two processes have been identified that provide the same level of particulate reduction. The first process is expected to incur $350,000 of fixed cost and add $50 of variable cost to each casting Spartan produces. The second process has fixed costs of $150,000 and adds $90 of variable cost per casting.a. What is the break-even quantity beyond which the first process is more attractive?b. What is the difference in total cost if the quantity produced is 10,000?
