Al is a medical doctor who conducts his practice as a sole proprietor. During 2021, he received cash of $672,400 for medical services. Of the amount collected, $43,200 was for services provided in 2020. At the end of 2021, Al had accounts receivable of $89,700, all for services rendered in 2021. In addition, at the end of the year, Al received $10,000 as an advance payment from a health maintenance organization (HMO) for services to be rendered in 2022. a.

The company has fixed expenses of $85,000 and variable expenses of $1.20 per package. Compute the contribution margin per package and the contribution margin ratio. Begin by identifying the formula to compute the contribution margin per package. Then compute the contribution margin per package. Factors which have necessitated evolution of strategichuman resource management / planning in organizations It is determined that the temperature (in degrees Fahrenheit) on a particular summer day between 9:00a.m. and 10:00p.m. is modeled by the function f(t)= -t^2+5.9T=87 , where t represents hours after noon. How many hours after noon does it reach the hottest temperature?

Jessie and Susan are working on the audit of Parker LLC, a medium-sized firm and distributor of cotton products throughout the continental United States. Jessie has just finished explaining why auditors obtain samples rather than test entire populations to Susan. Susan replies that although she understands, it would seem safer for the auditor just to test the entire population in order to be able to offer a higher level of assurance. Which of the following represents Jessie's best response to this? o The auditors tend to test samples more so than populations because the internal audit function routinely tests populations throughout the year o None of the choices is correct. o Auditors obtain and test a sample instead of the entire population because it would take too much time and be too expensive for the auditor to test the populations of all accounts. o Auditors only obtain and test samples because statistical theory holds that if the auditor obtains a sample size of at least ten percent of the population, the conclusions reached will be the same either way. Process A has fixed costs of $2500 and variable costs of $10 per unit. Process B has fixed costs of $1000 and variable costs of $25 per unit. What is the crossover point for Process A and Process B? If we need to manufacture 75 units, which Process should we choose? O Crossover = 200 units but we need 75 units so choose Process A O Crossover = 200 units but we need 75 units so choose Process B O Crossover 100 units but we need 75 units so choose Process A O Crossover 100 units but we need 75 units so choose Process B O Crossover is at fixed cost of $1500 for quantity of 75 units would you estimate for Halliford stock? Note: Remenber that growth rate is computed as: retention rate \( \times \) rate of return. The price per share is \( \$ \quad \) (Round to the nearest cent.) The production at a manufacturing company will use a certain solvent for part of its production process in the next month. Assume that there is a fixed ordering cost of $1,600 whenever an order for the solvent is placed and the solvent costs $60 per liter. Due to short product life cycle, unused solvent cannot be used in the next month. There will be a $15 disposal charge for each liter of solvent left over at the end of the month. If there is a shortage of solvent, the production process is seriously disrupted at a cost of $100 per liter short. Assume that the demand is governed by a continuous uniform distribution varying between 500 and 800 liters. (a) What is the optimal order-up-to quantity? (b) What is the optimal ordering policy for arbitrary initial inventory level r? (c) Assume you follow the inventory policy from (b). What is the total expected cost when the initial inventory I = 0? What is the total expected cost when the initial inventory x = 700? (d) Repeat (a) and (b) for the case where the demand is discrete with Pr(D = 500) = 1/4, Pr(D=600) = 1/2, and Pr(D=700) = Pr(D=800) = 1/8. Sam's Cat Hotel operates 52 weeks per year, 5 days per week, and uses a continuous review inventory system. It purchases kitty litter for $11.50 per bag. The following information is available about these bags. Refer to the standard normal table for z-values. > Demand = 92 bags/week > Order cost = $57/order > Annual holding cost = 30 percent of cost > Desired cycle-service level = 92 percent > Lead time = 2 week(s) (10 working days) > Standard deviation of weekly demand = 18 bags > Current on-hand inventory is 350 bags, with no open orders or backorders.
