A company had beginning inventory of 200 units costing $5. During the year they made the following purchases: April 20, 300 units of $6 each; June 14, 250 units at $7 each; August 12, 200 units at $8 each:; and November 15, 50 units at $9 each. There were 260 units remaining in inventory at the end of the year. What was the value of the ending inventory, assuming FIFO?

A) 1360.00
B) 2120.00
C) 2210.00
D) 1630.00

3. solve by graphing: y = 2x + 6 x + y = -3

What properties allow transformation to be used as a problem solving tool

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
