Casey Nelson is a divisional manager for Pigeon Company. His annual pay raises are largely determined by his division’s return o

baherus [9]

Answer:

NPV: $180,285.49

IRR: 21.336%

simple rate of return: 72.13%

Explanation:

6,100,000 investment

contribution margin 3,000,000

fixed expense: <u> 900,000 </u>

EBITA 2,100,000

We will calculate the NPV without the depreciation, as the depreciation is the distribution of the investment cost over the project life.

If we include the depreciation we will be counting the investment amount twice. Entirely at Time 0 and then subtracting on each cash inflow.

We will calculate the NPV at 20% as is the company's discount rate. Even if the current division returns are in 24% as the company accepts project which yields 20%.

$C \times \frac{1-(1+r)^{-time} }{rate} = PV\\$

C 2,100,000

time 5 years

rate 20% = 20/100 = 0.2

$2100000 \times \frac{1-(1+0.2)^{-5} }{0.2} = PV\\$

PV $6,280,285.49

NPV = PV of cash inflow - investment

6,280,285.49 - 6,100,000 = 180,285.49

<u>the IRR:</u>

The internal rate of return is the rate at which the NPV of a priject is zero.

We calculate this using excel formula IRR

or a financial calculator

it could also be done with trial and error using the PV tables.

<u>I will explain you in Excel</u>

FIrst, you write the inflow and outflow per year:

-6,100,000

2,100,000

2,100,000

2,100,000

2,100,000

2,100,000

then we write on another cell:

=IRR(

then, select the cells

and press enter

21.336%

<u>the simple rate of return:</u>

(total return - investment) / investment

(2,100,000 x 5 - 6,100,000) / 6,100,000 =

4,400,000 / 6,100,000 = 0.721311475 = 72.13%

A watch manufacturer incurs a variable cost of $10 per watch and fixed costs of $400,000. To earn a 25 percent markup on selling

WITCHER [35]

Answer:

$22.50 per unit

Explanation:

Mark -up is the percentage of cost that is earned as profit.

Using mark-up,

Selling price = Total cost + total profit

Total cot = Fixed cost + variable cost

Total costs = $400,000 + (10× 50,000)

= $900,000

Sales revenue = 125%× 900,000

= 1,125,000

Selling price per unit = Sales revenue/units

=1,125,000/50,000

= $22.50 per unit
