Final answer:
Robbie needs to consider continuing to buy coffee with a variable cost of $3 per pound or investing in a roaster with a variable cost of $1.60 per pound and fixed costs of $35,000 per year.
Step-by-step explanation:
Robbie of Forster's Market is considering two capacity options: continuing to buy coffee from a local supplier or investing in an industrial-sized coffee roaster. The current approach has variable costs of $3 per pound with coffee sold at $7 per pound. If Robbie invests in a coffee roaster, the variable costs would decrease to $1.60 per pound, but he would incur fixed costs of approximately $35,000 per year. This includes lease, power, training, and additional labor for the roaster that can process up to 40,000 pounds of coffee annually.
