Answer: $7,500
Step-by-step explanation:
3,000 units of LF normally costs:
= 3,000 * 30
= $90,000
7,000 units of 1B normally costs:
= 7,000 * 10
= $70,000
Together they cost:
= 90,000 + 70,000
= $160,000
Use this to calculate the proportional cost of LF from the lump sum:
= 90,000 / 160,000 * 120,000
= $67,500
Cost per unit of LF purchased at lump sum cost:
= 67,500 / 3,000 units
= $22.50
Gross profit:
= (Selling price - Cost per unit) * 1,000 units
= (30 - 22.50) * 1,000
= $7,500
