Final answer:
Rodney can buy 12 pounds of candy for $13.20, after finding out the cost per pound ($1.10) by dividing the initial cost of $5.50 by 5 pounds. Therefore, the correct option is B) 12 pounds
Step-by-step explanation:
When determining how many pounds of candy Rodney can buy for $13.20, we first need to establish the cost per pound of the candy based on the information given that 5 pounds cost $5.50. By dividing $5.50 by 5 pounds, we find that the candy costs $1.10 per pound. To find out how much candy Rodney can buy with $13.20, we then divide $13.20 by the cost per pound, which is $1.10.
The calculation will be as follows:
$13.20 ÷ $1.10/pound = 12 pounds of candy
Thus, Rodney can buy 12 pounds of candy for $13.20, making the answer to the question (B) 12 pounds.
