Question

select the double number line that shows the other values of packages and pencils. choose 1 answer: a: packages: 0,1,2,3,4; pencils: 0,12,24,36,48. b: (partial view of packages and pencils number lines)

Explanation:

Step1: Find the rate

From the given double number line, 3 packages correspond to 36 pencils. So the rate is $\frac{36}{3}=12$ pencils per package.

Step2: Check Option A

For Option A, when packages are 1, pencils should be 12; 2 packages should be $2\times12 = 24$; 3 packages (matches given 36); 4 packages should be $4\times12 = 48$. This matches the rate.

Step3: Check Option B (incomplete, but A is valid)

Since Option A follows the rate of 12 pencils per package, it's the correct double number line.

Answer:

A. Packages: 0, 1, 2, 3, 4; Pencils: 0, 12, 24, 36, 48
