Final answer:
To find out how many pounds of candy Rodney can buy for $13.20, we can set up a proportion using the given information: 5 pounds of candy / $5.50 = x pounds of candy / $13.20. After cross-multiplying and simplifying, we find that Rodney can buy approximately 12 pounds of candy for $13.20.
Step-by-step explanation:
To find out how many pounds of candy Rodney can buy for $13.20, we need to determine the cost per pound of candy.
We can set up a proportion using the given information:
5 pounds of candy / $5.50 = x pounds of candy / $13.20
Cross-multiplying, we get:
5 pounds of candy * $13.20 = x pounds of candy * $5.50
Simplifying, we find:
x pounds of candy = (5 pounds of candy * $13.20) / $5.50
Calculating the value, we determine that Rodney can buy approximately 12 pounds of candy for $13.20.
