On July 1, 2016, the Morgan County School District received a $51,000 gift from a local civic organization with the stipulation that, on June 30 of each year, $3,600 plus any interest earnings on the unspent principal be awarded as a college scholarship to the high school graduate with the highest academic average. A private-purpose trust fund, the Civic Scholarship Fund, was created.

1. On July 1, 2016, the gift was received and immediately invested.
2. On June 30, 2017, $3,600 of the principal was converted into cash. In addition, $2,600 of interest was received.
3. On June 30, the $6,200 was awarded to a student who had maintained a 4.0 grade point average throughout each of her four years.
4. The nominal accounts were closed.
   

Required:
a. Record the above transactions on the books of the Civic Scholarship Fund.
b. Prepare a Statement of Changes in Fiduciary Net Position for the Civic Scholarship Fund for the year ended June 30, 2017.

Find the linear space of eigenfunctions for the problem with periodic boundary conditions

u′′(x) = λu(x)

u(0) = u(2π)

u′(0) = u′(2π)

for (a) λ = −1 (b) λ = 0 (c) λ = 1.

Note that you should look for nontrivial eigenfunctions

The federal government calculates its budget on a fiscal year that begins each year on October 1 and ends the following September 30. At the beginning of the 2003-2004 fiscal year, the Department of Finance forecast that the federal budget surplus for the fiscal year would be $4.0 billion. The actual budget surplus for the fiscal year was $9.1 billion. Federal expenditures were $1.7 billion less than the Department had forecast, and federal revenue was $1.5 billion more that the Department had forecast. The remainder of the surplus came from lower-than-forecast debt charges. a) Is it likely that the economy grew faster or more slowly during fiscal 2003-2004 than the Department of Finance had expected? Explain your reasoning. b) Suppose that the federal government was committed to balancing the budget each year. What actions of the government would have led to a balanced budget? And what will be the economic consequences? Explain. c) Does the surprise surplus during fiscal 2003-2004 provide any insight into difficulties that might arise in trying to balance the budget every year? Explain.
