Bargain Rental Car offers rental cars in an off-airport location near a major tourist destination in California. Management would like to better understand the variable and fixed portions of it car washing costs. The company operates its own car wash facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the variable portion of its car washing costs relates to the number of rental returns. Accordingly, the following data have been compiled:

Required:

1. Prepare a scattergraph plot. (Place car wash costs on the vertical axis and rental returns on the horizontal axis.)

Instructions:

1. On the graph below, use the point tool (January) to plot rental returns on the horizontal axis and car wash costs on the vertical axis.

2. Repeat the same process for the plotter tools (February to December).

3. To enter exact coordinates, click on the point and enter the values of x and y.

4. To remove a point from the graph, click on the point and select delete option.

3. Sydney Rangers Inc operates remote parking lots near major airports. The board of directors of this family-owned company believes that Sydney Rangers could earn an additional $2 million income before interest and taxes by expanding into new markets. However, the $5 million that the business needs for growth cannot be raised within the family. The directors, who strongly wish to retain family control of the company, must consider issuing securities to outsiders.
Sydney Rangers’s Plan 1 is to borrow at 6%. Plan 2 is to issue 100,000 common shares. Plan 3 is to issue 100,000 non-voting, $3.75 preferred shares ( $3.75 is the annual dividend paid on each preferred share). Sydney Rangers currently has net income of $3.5 million and 1 million common shares outstanding. The company’s income tax rate is 25%.
Requirements:
1. Prepare an analysis to determine which plan will result in the highest earning per common share.
2. Recommend one plan to the board of directors. Explain your reasons.

Eastern Aviation operated both an airline and several restaurants located near airports. During the year just ended, all restaurant operations were discontinued and the following operating results were reported.

All of these amounts are before income taxes unless indicated otherwise. The company's income tax rate is 40 percent. The nonrecurring loss resulted from damage to a warehouse that is not related to the discontinued restaurant operations. Eastern Aviation had 1,000,000 shares of capital stock outstanding throughout the year.

Required:

a. Prepare a condensed income statement, including proper presentation of the discontinued restaurant operations and the nonrecurring loss. Include all appropriate earnings per share figures.

b. Assume that you expect the profitability of Eastern Aviation operations to decline by 5 percent next year, and the profitability of the restaurants to decline by 10 percent. What is your estimate of the company’s net earnings per share next year?

1.A 1000 ephemeral stream segment along the Town Creek near Tupelo, MS has a width of 30-m. The difference in elevation of the bottom channel for the upstream to the downstream section is 0.5m. A triangular hydrograph cumulating 10-cm of runoff that begins at 0m3/s reaches a peak of 35m3/s after the first hour of flow and returns to 0m3/s at the time 2.8-hr.If no lateral or overbank inflow is observed along the reach:

a.(15pts) Compute the outflow hydrograph for this reach selecting a time step of 0.1hr, a travel time constant of 0.285 hr and a weighting factor o f0.35.(use 4 decimal places for the outflow hydrograph to determine the routing time to reach the 0m3/s)(As you could submit your routingin Excel, hand/typing calculation are required for the time step that corresponds to your last digit of the net id.
