Question

read the problem. carlos got 130 pieces of candy on halloween, and 39 of them were lollipops. what percent of the pieces of candy were lollipops? pick the model that represents the problem. what percent of the pieces of candy were lollipops? %

Explanation:

Step1: Set up percentage formula

To find what percent 39 is of 130, use the formula:
$$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100\%$$
Here, the part is 39 (lollipops) and the whole is 130 (total candy).

Step2: Substitute values and calculate

$$\text{Percentage} = \frac{39}{130} \times 100\%$$
First, simplify $\frac{39}{130} = 0.3$, then multiply by 100%:
$$0.3 \times 100\% = 30\%$$

Step3: Identify correct model

The top model divides 130 into 10 equal parts (each part = 13, 3 parts = 39), which matches the 30% (3 out of 10 parts) calculation.

Answer:

1. Correct model: The top (purple) bar model
2. Final percentage: 30%
