Final answer:
The action referred to would be multiplying the number of pounds of broccoli (z) by the price per pound ($1.25) to find the total cost. This is similar to multiplying quantities of other items by their unit price to calculate total spending.
Step-by-step explanation:
Ignoring any typos or irrelevant parts of the question, when calculating the total cost of buying z pounds of broccoli at a price of $1.25 per pound, you simply multiply the number of pounds z by the price per pound. This is an application of basic algebra and arithmetic to determine the total expense related to the purchase of a given weight of an item, in this case, broccoli.
Using unit price to find the total spending is a common math operation in various real-life situations, similar to calculating costs for other products like apples, bananas, grapes, and raspberries. For instance, 10 apples at 50 cents each will cost $5.00, which follows the same logic - multiplying the quantity (10 apples) by the unit price (50 cents per apple) to get the total (5.00 dollars).
