Periodic inventory using FIFO, LIFO, and weighted average cost methods The units of an item available for sale during the year were as follows: Date Line Item Description Units Cost per Unit Amount Jan. 1 Inventory 16 units at $49 $784 Aug. 13 Purchase 5 units at $50 250 Nov. 30 Purchase 4 units at $52 208 Available for sale 25 units $1,242 There are 15 units of the item in the physical inventory at December 31. The periodic inventory system is used. Determine the inventory cost using the (a) first-in, first-out (FIFO) method; (b) last-in, first-out (LIFO) method; and (c) weighted average cost method (round per-unit cost to two decimal places and your final answer to the nearest whole dollar). Line Item Description Amount a. First-in, first-out (FIFO) method $fill in the blank 1 b. Last-in, first-out (LIFO) method $fill in the blank 2 c. Weighted average cost method

EXAMPLE 6 Find the scalar projection and vector projection of b = (4, 2, 1) onto a = (-2, 4, 3). SOLUTION Since $|a| = \sqrt{(-2)^2 + 4^2 + 3^2} = \sqrt{29}$, the scalar projection of b onto a is $comp_a b = \frac{a \cdot b}{|a|} = \frac{(-2)(4) + 4(2) + 3(1)}{\sqrt{29}}$ $= \frac{3\sqrt{29}}{29}$ The vector projection is this scalar projection times the unit vector in the direction of a, below. $proj_a b = \frac{3\sqrt{29}}{29} \cdot \frac{a}{|a|} = \frac{3\sqrt{29}}{29} \cdot a$
