For example, electricity costs are $1,400 per month plus $0.06 per car washed. The company expects to wash 8,200 cars in August and to collect an average of $6.10 per car washed.

The actual operating results for August are as follows:

Required:

Calculate the company's revenue and spending variances for August. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

In the early 20th century, the French Canadian microbiologist Félix d’Hérelle used a virus called a bacteriophage (“phage”) to successfully treat some diseases caused by bacteria, such as dysentery and cholera. Subsequent experiments with “phage therapy” yielded mixed results; however, and enthusiasm quickly waned—especially once antibiotics became available in the 1940s. The therapy is not currently approved in the United States.

Phage therapy involves obtaining a pure culture of a disease-causing bacterium and exposing samples of the culture to different phages to see which ones kill the bacterium. The successful phage is then administered to a patient. For skin infections, the phage is applied directly to the infected area. For systemic diseases, the phage may be given orally or delivered intravenously.

Imagine you are part of a hospital medical team conveyed to treat Jerry, a 71-year-old diabetic patient, who has been suffering from a persistent infection on his foot. His doctor has tried multiple topical antibiotics, but the infection continues to worsen, so the doctor admitted him to your hospital for a new intravenous antibiotic treatment. To Jerry’s relief, the infection cleared up; however, two weeks later, the infection returned—worse than ever. Jerry’s doctor explains that the bacterium causing the infection is a multidrug resistant strain and that Jerry’s foot will need to be amputated.

Jerry’s sister, a nurse, mentions that she studied bacteriophages and asks the doctor whether phage therapy is a treatment option.

As a member of Jerry’s medical team, answer these questions:

• How would you respond to Jerry’s sister?

• Which type of phage would be used for phage therapy: a lytic or a lysogenic phage?

• What are the drawbacks of phage therapy? What are the advantages?

Suppose that you won an exclusive bid to sell Christmas trees from National Park Service (NPS). However, NPS requires that you plant one and a half multiple of any number of trees you cut. For example, if you cut 4 trees, you have to plant 8 trees. If you cut 9, you have to plant 27 trees. The NPS may argue that the number of trees that survive is proportional to the number of tree that you grow. Or, they might just do so to prevent you from cutting all trees. Assume further that the cost of cutting and transporting a tree is $2. The cost of growing a tree is $1.  
Questions:
A.) Write an equation that describes total cost of cutting any number of trees.
B.) Graph total cost function
C.) Derive and graph the average cost equation
D.) Derive and graph the marginal cost equation

Now, assume that as a monopolist, you can sell Christmas trees directly to customers and charge them a higher retail price. Or, on the other hand, you can sell Christmas tree to retail stores and charge them lower wholesale price. It is logical to assume that ordinary customer demand tends to be less elastic than the demand of retail stores. Assume that you estimate the demand of retail stores and customers and find:

P= 3000 – 0.5Q  (Wholesale demand)
P= 2000-2Q   (Retail Demand)

Questions
E) Write the equations that describe total revenue for each market
F.) Graph your total revenue equations
G.) Derive the marginal revenue equations for each market
H.) Graph your answer
E
I.) Find the profit maximizing price and quantity for each market
J.) Write the equation that describe total revenue for the two market combined
K.) Derive the marginal revenue equations for the two markets combined
L.) Graph your answer
M.) Find the profit maximizing price and quantity for both markets combined.
N.) What is better, to combine both market and charge a single price or segregate the two markets and charge different prices? Explain your answer

A group of 500 unicorns have magically appeared at Griffith Park. Researchers have speculated social distancing restrictions have enabled them to grace our lands. Interestingly, the genetic makeup of unicorns is unlike that of humans. They are triploid species, meaning that 3 alleles make up a given genotype. Researchers have observed variation in their coat colors with 40 unicorns having red coats (WWw), 250 white coats (www), 110 black coats (WWW), and 100 blue coats (wwW).

A. Calculate the genotype frequency for each given genotype: WWw, www, WWW, and wwW.

B. Calculate the allele frequency for each given allele: W and w.

C. Fast forward 50 years into the future, a new generation of unicorns have emerged with a total of 150. Researchers make the following observation: 5 red coats (WWw), 130 white coats (www), 7 black coats (WWW), and 8 blue coats (wwW). Compare this generation to the parent generation. Is the new generation of unicorns undergoing Hardy Weinberg Equilibrium? If not, list at least 2 evolutionary forces that may have occurred.

* father and sister treated for malignant melanoma in the last 10 years
* Anxious that the mole might be cancer and require surgery

objective data

* Has a 6mm nevus blue black in color, scalloped with vaguely defined borders
* Two dysplastic nevi found on neck
