Answer 1

The correct ratio of the cost to the number of pounds is 12.50/10, with an equivalent fraction showing the unit rate of $1.25 per pound, indicating that the cost of apples is $1.25 per pound.

Step-by-step explanation:

To find the ratio of the cost to the number of pounds of apples, you divide the total cost by the total number of pounds. Therefore, the ratio of the cost ($12.50) to the number of pounds (10 pounds) is written as the fraction $12.50/10. To find an equivalent fraction with a denominator of 1, you divide $12.50 by 10, which gives you $1.25 per pound. This is the unit rate, and it describes the cost of apples per pound.

The correct choice based on the information given is C) 12.50/10, 1.25, $1.25 per pound.
