Answer: $54,400
Step-by-step explanation:
The First in First Out inventory costing method sells earlier purchases first and then sells later ones.
The 80 units sold on March 10 will come from the beginning balance of 400 units leaving it with 320 units.
Of the 480 units sold on October 30, 320 will come from the beginning inventory balance of 320 units leaving;
= 480 - 320
= 160 units.
These 160 units will come from the 800 units purchased on June 10 which means the costing inventory is;
= 800 - 160
= 640 units
Cost of 640 units;
= 640 * 85
= $54,400
