Answer:
Lamar's operating profits will increase by $1,900
Step-by-step explanation:
Incremental costs are the change in total cost that arise due to a decision made. In case of order of Boston Company incremental costs is only the variable part of the cost associated withthe production of tolls. Fixed costs are already incurred and it can be avoidable.
Cost per unit = $1.83
Variable cost = Total cost per unit - Fixed cost per unit = $1.83 - $0.27 = $1.56
Marginal Contribution per unit = Selling price - variable cost = $1.75 - $1.56 = $0.19
Total addition to operating profit = $0.19 x 10,000 = $1,900
