Question

Given that the expression "p dollars for every q items" describes a unit price, which statement must be true?

A) p=1
B) p=q
C) q=1
D) pq=1

Answer 1

The unit price described by "p dollars for every q items" does not necessitate any of the given conditions to be true (A) p=1, B) p=q, C) q=1, or D) pq=1. It is simply the total cost p divided by the number of items q to find the price per item.

Step-by-step explanation:

The expression "p dollars for every q items" represents a unit price, meaning the cost per single item. The correct statement regarding this expression is that none of the given options necessarily have to be true. None of the statements A) p=1, B) p=q, C) q=1, or D) pq=1 inherently describe a unit price. A unit price is simply calculated by dividing the total price p by the number of items q. This gives us the price per individual item. The options presented imply specific conditions that are not required for the concept of a unit price.
