Helen holds 1,000 shares of fizbo inc. stock that she purchased 11 months ago. the stock has done very well and has appreciated $20/share since helen bought the stock. when sold, the stock will be taxed at capital gains rates (the long-term rate is 15 percent and the short-term rate is the taxpayer’s marginal tax rate). ignore the time value of money. if helen’s marginal tax rate is 35 percent, how much would she save by holding the stock an additional month before selling?

if shares are hold for more than a month then tax that can be saved is $4000

Step-by-step explanation:

Given Data:

Per share increase in price = $20

Number  of shares = 1000

Long term tax rate 15%

short term rate 35%

Total capital gain = 1000 ×20 = 20000

Tax rate when hold  for one year extra = 20000 × 15% = 3000

Tax rate for short term, capital gain  20000 × 35% = 7000

So if shares are hold for more than a month then tax that can be saved is

=  (7000 - 3000) = 4000

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
