Answer:

the cost for the running the boarding school for 600 students is $61000

Explanation:

Let x be the constant  cost  and y be the variable cost . then according to the given condition

total cost=<em><u> x +25y= $3500-------1</u></em>

<u><em>x +50y= $6000----------2</em></u>

Subtracting 1 from 25y= 2500

<u><em>y= 2500/25= $100-----------3</em></u>

<em><u>Putting the value of y from 3 in 1 </u></em>

x+ 25(100)= 3500

x+ 2500= 3500

<u><em>x= 1000$---------4</em></u>

<u><em>Putting the value of y from 3 in 2</em></u>

x+ 50(100)= 6000

x+ 5000=6000

<u><em>x= 1000$----------5</em></u>

<u><em>Putting the values of x and y in 1  for 600 students</em></u>

1000+ 600(100) =1000+ 60000= $61000

Juli2301 [7.4K]

Answer: Decrease, decrease

Explanation: Substitute goods are those goods that are used in place of each other. When the price of a substitute good falls, it becomes more attractive to the consumers. Here, wood planks and wood beams are substitutes to each other. So, when price of wood plank falls, demand for wood beams will decrease, shifting the demand curve to the left. As a result, of this the equilibrium price of wood beams and the quantity of wood beams will also decrease.

yanalaym [24]

Answer:Yield to maturity is 9.59%;  After tax cost of debt =7.672%

Explanation:

 A)   Yield to maturity ={ C + (FV-PV)/t} /  {(FV +PV)/2}

Where C – Interest payment    = $90

FV – Face value of the security

= $1000

PV – Present value/curent market value = $960

t – years it takes the security to reach maturity= 10 years

imputing the values and calculating,

yield to maturity ={ C + (FV-PV)/t} /  {(FV +PV)/2}

= $90 + (1000-960)/10} / 1000 + 960 /2

$90 + 4= $94 /980= 0.0959

therefore Yield to maturity is 9.59%

B)   After tax cost of debt =    Yield To Maturity  x (1 - tax rate)

=9.59% x (1-20%)= 9.59% x (1-0.2 )= 9.59% x 0.8 =

9.59 % x 80%=7.672%
