Final answer:
A unit price is the price for one unit of an item. Among the options provided, $3.00 for every pound represents a unit price because it tells us the cost per single pound.
Step-by-step explanation:
The question asks which rate describes a unit price. A unit price is the cost per single item or measure. It is calculated by dividing the total price by the number of units. In the context of the examples provided, a unit price is expressed as a cost for one lemon, one pound, one slice of pizza, or one bottle.
- $1.00 for 2 lemons => $0.50 per lemon
- $3.00 for every pound => $3.00 per pound (this is a unit price)
- $4.00 for 3 slices of pizza => $1.33 per slice of pizza
- $6.00 for every 6 bottles => $1.00 per bottle
Therefore, out of the provided options, $3.00 for every pound best represents a unit price as it is a rate describing the cost of one pound.
