Answer:
d. $7,500
Step-by-step explanation:
The computation of the gross profit is shown below:
But before that following calculations need to be done
Tota sales are
= 3000 units × $30 + 7,000 units × $10
= $90,000 + $70,00 0
= $160,000
Now the weighted of LG is
= $90,000 ÷ $160,000 × $120,000
= $67,500
The unit cost would be
= $67,500 ÷ 3,000 units
= $22.5 per unit
Finally the gross profit is
= (Sales price - cost price) × number of units sold
= ($30 - $22.5) × 1,000
= $7,500
hence, the correct option is d. $7,500
