The income tax and social insurance systems of Marxland are as follows. The average tax rate on each citizen's income is  $100 \%$. In order to ensure that everyone has an identical after-tax income, a social insurance system then distributes transfers to each citizen. In other words, an equal portion of the income tax money is distributed to each citizen (through a government transfer payment). What motivates a single citizen to go to work and make money? What will Marxland's overall tax take be? What will each citizen's post-tax income (including the transfer payment) be? Do you believe a tax system that produces absolute equality will be successful?

Your challenge will be to work with a partner to create a parabola puzzle for another pair of students to solve. Follow the directions below to create a puzzle that will make them think and allow them to show off their algebra skills. When you are ready, you will trade puzzles with another pair and attempt to solve theirs. a. With your partner, decide on an equation for a parabola and then identify three points that lie on its graph. Keep track of how you came up with your equation and how you chose your points. Be ready to share strategies. b. Write the coordinates of the three points on an index card or small slip of paper to give to another pair of students. Be sure you keep a copy of your equation so you can check their work later. c. Trade points with another pair and work with your partner to solve their puzzle. When you are confident of your equation, check your work with the pair that wrote it.

Simplify the following expressions, writing your answer with only positive exponents.

The earnings of a PGA Tour golfer are determined by performance in tournaments. A study analyzed tour data to determine the financial return for certain skills of professional golfers. The sample consisted of 393 golfers competing in one or both of the 2002 and 2008 seasons. The most significant factors that contribute to earnings were the percent of attempts a player was able to hit the green in regulation (GIR) , the number of times that a golfer made par or better after hitting a bunker divided by the number of bunkers that were hit (SS), the average of putts after reaching the green (AvePutt), and the number of PGA events entered (Events). The resulting coefficients from multiple regression to predict yearly earnings (in $) are:

State the prediction equation for a PGA Tour golfer's yearly earnings.

Cell Sites A cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones. The numbers of cell sites from $1985$ through $2008$ can be modeled by

$$y=\frac{237,101}{1+1950e^{-0.355t}}$$

where $t$ represents the year, with $t=5$ corresponding to $1985.$ (Source: CTIA-The Wireless Association)

Find the vertex for the parabola whose equation is given by writing the equation in the form $y=a x^{2}+b x+c$. $y=(x-3)^{2}+2$

On January 1, 2018, Essence Communications issued $\$ 800,000$ of its 10-year, $8 \%$ bonds for $\$ 700,302$. The bonds were priced to yield $10 \%$. Interest is payable semiannually on June 30 and December 31 . Essence Communications records interest at thel effective rate and elected the option to report these bonds at their fair value. On December 31, 2018, the market interest rate for bonds of similar risk and maturity was $9 \%$. The bonds are not traded on an active exchange. The increase in the market interest rate was due to a $1 \%$ increase in general (riskfree) interest rates.

Required:

1. Using the information provided, estimate the fair value of the bonds at December 31, 2018.
2. Prepare the journal entry to record interest on June 30,2018 (the first interest payment).
3. Prepare the journal entry to record interest on December 31,2018 (the second interest payment).
4. Prepare the journal entry to adjust the bonds to their fair value for presentation in the December 31,2018 , balance sheet.
