Preliminary Analytical Procedures; Required: Perform preliminary analytical procedures analysis on the current-year unaudited financial statements for the purpose of identifying accounts that you want to investigate further. Calculate comparative and common-size (to 2 decimal points) financial statements. Add subtotals for operating income, current assets, current liabilities, & total liabilities in the statements. Assume that all sales are credit sales. Please set up 6 columns in an excel file in the following order: 1) Prior year in $, 2) prior year common-sized, 3) current year in $,4) current year common-sized 5) $ change between current yr. and prior yr., 6) % change between current yr. and prior yr. Also calculate 5 Balance Sheet ratios, and 5 Operations Ratios. For the ratios, calculate the prior year, current year, and percent change. Note: There were no dividends paid at any time. The co. is to maintain a current ratio of 2.0 , per the bank. Once your calculations are completed, identify at least 4 accounts that you should investigate further in your substantive testing. Explain why you want to investigate these accounts.

We've worked out two equations to describe the supply/demand for a high-speed train route, where C is the cost of the train ticket and V is the volume of passengers using the train (in 1000s of passengers). SUPPLY EQUATION: C=52V-32 DEMAND EQUATION: C=20V+16 What is the equilibrium cost of ticket that people are willing to pay?

The two pipes shown contain hexylene glycol, which causes the differential pressure reading of the mercury manometer, i.e., the manometer deflection, to be initially $h = 1.2 \text{ft}$. The pressure in pipe A is then increased by 0.75 psi and the pressure in pipe B reduced by 0.2 psi. What is the resulting manometer deflection after the changes in pressures in the pipe? The specific gravity of hexylene glycol may be taken to be 0.923 and that of mercury to be 13.55. Hint: Working with piezometric heads may be advantageous.
