Determine the capitalized cost of a permanent roadside historical marker that has a first cost of $75,000 and a maintenance cost
densk [106]

Answer:

The capitalized cost is $ 84,667.20

Explanation:

First of all please note that the cost of $ 75,000 is already the present cost.

The cost of $3200 which occurs every 3 years can be converted into a value using factor A/F for one life cycle.

The capitalized cost then can be calculated as follows :

CC = $ 75,000 + $ 3200(A/F, 10%, 3 years)/interest

CC = $ 75,000 + $ 3,200(0.3021)/0.1

CC = $ 75,000 + $ 9,667.2

CC = $ 84,667.20

The College Bookstore sells a unique calculator to college students. The demand for this calculator has a normal distribution wi
Strike441 [17]

Answer:

Option (A) is correct.

Explanation:

Given that,

Mean daily demand, M = 20 calculators per day

Standard deviation, SD = 4 calculators per day

Lead time for this calculator, L = 9 days

z-critical value (for 95% in-stock probability) = 1.65 (From z tables)

Normal consumption during lead-time:

= Mean daily demand × Lead time

= 20 × 9

= 180 units of calculator

Safety Stock = z value × SD × L^(0.5)

                     = 1.65 × 4 × (9)^(0.5)

                     = 1.65 × 4 × 3

                     = 19.8 units

Reorder Point = Normal consumption during lead-time + Safety Stock

                        = 180 units  + 19.8 units

                        = 199.8 or 200 units (Approx)

Rising peanut prices have forced peanut butter makers to raise the price of a jar of peanut butter from $2 to $3 per jar, causin
Vanyuwa [196]

Answer:

37.5%

Explanation:

The percentage change in the price of a jar of peanut butter, using the midpoint method, is:

P_B = \frac{3-2}{\frac{3+2}{2}}*100=40\%

The percentage change in sales of jelly is 15%.

The cross elasticity of demand between peanut butter and jelly is:

E = \frac{15\%}{40\%}*100\%\\E=37.5\%

The cross elasticity of demand is 37.5%
