Why do cells contain only a small amount of ATP? A. ATP cannot store large amounts of energy for a long time. B. ATP releases energy too quickly. C. ATP cannot carry out active transport. D. ATP has only two phosphate groups.

Cub Company, a calendar-year entity, had 2,100 geothermal heating pumps in its beginning inventory for 20X1. On December 31, 20X0, the heating pumps had been adjusted down to $850 per unit from an actual cost of$920 per unit. It was the lower of cost or market. Cub purchased no additional units during 20X1. The following additional information is provided for 20X1:

$$\begin{array}{clrr} && \textbf{Inventory} & \textbf{Unit Market}\\ \textbf{Quarter} & \textbf{Date} & \textbf{(units)} & \textbf{Value}\\ \\ 1 & \text{March 31, 20X1} & 1,700 & \$845\\ 2 & \text{June 30, 20X1} & 1,400 & 860\\ 3 & \text{September 30, 20X1} & 1,300 & 830\\ 4 & \text{December 31, 20X1} & 900 & 840\\ \end{array}$$

Required

Case 1: The company does not have sufficient experience with the seasonal market for geothermal pumps and assumes that any reductions in market value during the year will be permanent.

$\quad$ (1) Determine the cost of goods sold for each quarter.

$\quad$ (2) Verify the total cost of goods sold by computing annual cost of goods sold on a lower-of-cost-or-market basis.
