Answer 2

Calculating the Number of Red Pencils

To calculate the number of red pencils, we can use the given information that there are 20 pencils in total, the number of blue pencils is 8 times the number of green pencils, and the number of red pencils is less than the number of blue pencils.

Let's denote: - Number of green pencils as g - Number of blue pencils as 8g (8 times the number of green pencils) - Number of red pencils as r

We know that the total number of pencils is 20: g + 8g + r = 20

We also know that the number of red pencils is less than the number of blue pencils: r < 8g

Let's solve for the number of red pencils.

Solving for the Number of Red Pencils

First, we can express the number of green pencils in terms of the number of red pencils using the given information that the number of blue pencils is 8 times the number of green pencils: g = 1/8 * (20 - r)

Substitute this expression for g into the equation r < 8g to solve for r.

Calculation

Let's calculate the number of red pencils using the given information.
