Answer:
b. $11,250
Explanation:
We are asked to know the gross profit:
gross profit: sales revenue - COGS
in this case sales revenue 1,000 units x $ 30 = 30,000
for COGS we will calculate with weighted average based on the sales price:
3,000 x 30 + 7,000 x 10 = 90,000 + 70,000 = 160,000
the cost of 160,000 dollars of sale is 100,000
we cross multiply for 30,000:
100,000 / 160,000 x 30,000 = 18,750 cost
now we solve for gross profit:
sales 30,000 - cost 18,750 = 11.250
