Answer:
The operating profit will increase by total contribution earned from the order completion of 300 meals.
Explanation:
The company is will to pay $3.35 per meal which means $1005 (3.35*300) is the total amount the company will pay to Maria for the preparation of the order. Suppose that the total variable cost for preparing this order is $505 then the contribution will be:
Total Sales - Total Variable cost = Total Contribution
By putting values:
$1005 - $505 = $500 is the Total contribution that the company has earned. This $500 will increase the operating profit by the $500 because their are no fixed costs or variable administration cost increase. So the net increase in the operating cost will be this $500.
