If Bread and Butter Bakers meet their sales goal, their net profit per month is $11,500
Explanation:
Bread and Butter plans to use 10,000 pounds of flour per month at a price of $2.00 per pound with an additional variable expense per loaf of $1.50. They hope to sell 10,000 loaves of bread.
Total variable expense = 10,000 x $2.00 + 10,000 x $1.50 = $35,000
Total sales = 10,000 x $6.00 = $60,000
Net profit = Total sales - Total variable expense - fixed costs = $60,000 - $35,000 - $13,500 = $11,500
