Step-by-step explanation:
Giving the following information:
Maribel:
Sales= $6,000
Variable cost= $5,900
Contribution margin= $100
Jessica:
Sales= $10,700
Variable cost= $7,100
Contribution margin= $3,600
Timothy:
Sales= $12,350
Variable costs= $12,000
Contribution margin= $350
The total fixed costs for the month amount to $3,500.
Net operating income= contribution margin - fixed costs
Net operating income= (100 + 3,600 + 350) - 3,500= $550
