Final answer:
To calculate the total quantity sold for products in the kitchen category using the total row, you should add up the values in the total row. This sum represents the overall quantity sold.
Step-by-step explanation:
To calculate the total quantity sold for products in the kitchen category using the total row, you would typically add up the values in the total row.
Each value in the total row represents the total quantity sold of a single product, and the sum of these values will give you the aggregate quantity sold of all products in that category. This process adheres to the concept that the total of a set of numbers is found by adding the numbers together.
In economic contexts, such as determining total revenue or total cost, you frequently multiply the price and quantity of each item to find the total amount. For instance, when calculating total revenue, you multiply the price and quantity at each point on the demand curve.
Similarly, total cost can be found by multiplying the cost associated with each unit of quantity. Following this, marginal revenue and marginal costs are calculated by taking the change in revenue or cost and dividing it by the change in quantity, while average cost is found by dividing total cost by quantity.
Therefore, the correct answer is 1) By adding up the values in the total row.
