Answer:
Step-by-step explanation:
using the weighted average method
average cost per unit = total cost/total units
begning stock 70*30 = 2100
purchases 10*10 = 100
2200/80
w. average per unit cost = 27.5
purchases 15*12 = 180
2200+180=2380/(100+15)
w. average per unit cost = 20.70
there is no purchase after the 5/30 therefore the cost of ending stock under average method will be 20.7 per unit and 20.7*10 =207 total closing cost.
