1. Pearl uses all her money in buying two goods, travel goods ($x_1$) and groceries ($x_2$). Her utility function is: $u(x_1, x_2) = \begin{cases} \sqrt{x_1 - k} + \sqrt{x_2} & \text{if } x_1 \ge k, \\ 0.1x_2 & \text{if } x_1 < k, \end{cases}$ where $k > 0$ is a constant. This preference indicates that if she consumes $x_1$, she must have at least $k$ units; otherwise, she prefers to have none at all (i.e., no travels). Let the prices of $x_1$ and $x_2$ be $p_1$ and $p_2$, respectively. She has income $I$. a. Find the Marshallian demand function for each good. Draw the demand curves for both goods. b. How will the demand curves change when $k$ increases? Explain your finding. c. Currently, $k = 2$, $p_1 = 1$, $p_2 = 1$ and $I = 10$. Find the optimal choice ($x_1^*$, $x_2^*$). Moreover, find the own-price elasticity of demand $\epsilon_{11}$, cross-price elasticity $\epsilon_{12}$, and income elasticity $\epsilon_{I1}$ measured at ($x_1^*$, $x_2^*$). d. Following c., it is expected that the price of travel goods will increase to $p_1 = 2$. Other things remain the same. Compute the total effect, substitution effect, and income effect caused by the price change in terms of $x_1$. Draw a picture to show them.

What is the difference between a ligand and a complex ion? A ligand is a charged species consisting of a central metal ion bonded to one or more ligands, while a complex ion donates electrons to a metal atom or ion. A ligand is a type of complex ion, while a complex ion is a type of ligand. A ligand donates electrons to a metal atom or ion, while a complex ion is a charged species consisting of a central metal ion bonded to one or more ligands. A ligand is a molecule or ion that forms a coordinate bond with a metal atom or ion, while a complex ion is a molecule or ion that forms a covalent bond with a metal atom or ion.

Let \( f(x, y, z)=x^{2} z \) and let \( C \) be the curve given by \( \mathbf{r}(t)=\left\langle 2 e^{t}, 2 \sqrt{2} t, 2 e^{-t}\right\rangle \) for \( 0 \leq t \leq 1 \). Compute \( \int_{C} f d s \). (Use symbolic notation and fractions where needed.) \[ \int_{C} f d s= \] \( \square \)

Gladstone Company tracks the number of units purchased and sold throughout each accounting period but applies its inventory costing method at the end of each period, as if it uses a periodic inventory system. Assume its accounting records provided the following information at the end of the annual accounting period, December 31. Transactions Units Beginning inventory, January 1 2,800 Unit Cost $60 Transactions during the year: a. Purchase, January 30 4,250 74 b. Sale, March 14 ($100 each) (2,450) c. Purchase, May 1 2,950 90 d. Sale, August 31 ($100 each) (2,900) Assuming that for Specific identification method (item 1d) the March 14 sale was selected two-fifths from the beginning inventory and three-fifths from the purchase of January 30. Assume that the sale of August 31 was selected from the remainder of the beginning inventory, with the balance from the purchase of May 1. Required: 1. Compute the amount of goods available for sale, ending inventory, and cost of goods sold at December 31 under each of the following inventory costing methods: (Round intermediate calculations to 2 decimal places and final answers to the nearest whole dollar amount.) Amount of Goods Available for Sale Ending Inventory Cost of Goods Sold a. Last-in, first-out $ 748,000 b. Weighted average cost $ 748,000 c. First-in, first-out $ 748,000 d.
