In its first month of operations, Wildhorse Co. made three purchases of merchandise in the following sequence: (1) 180 units at $9, (2) 560 units at $10, and (3) 125 units at $11. Assuming there are 250 units on hand, compute the cost of the ending inventory under the (a) FIFO method and (b) LIFO method. Wildhorse uses a periodic inventory system.

Until recently, hamburgers at the city sports arena cost $4.70 each. the food concessionaire sold an average of 13 comma 000 hamburgers on game night. when the price was raised to $5.40, hamburger sales dropped off to an average of 6 comma 000 per night. (a) assuming a linear demand curve, find the price of a hamburger that will maximize the nightly hamburger revenue. (b) if the concessionaire had fixed costs of $1 comma 500 per night and the variable cost is $0.60 per hamburger, find the price of a hamburger that will maximize the nightly hamburger profit.
