Question

Casey, a second-grade boy, is raising caterpillars which each have the same number of legs. Let C represent the number of caterpillars Casey has, and I represent the number of legs each caterpillar has. Write an expression for the total number of legs that the caterpillars and Casey have together.

Answer 1

The expression for the total number of legs that the caterpillars and Casey have together is C * I + 2.

Step-by-step explanation:

Let's start by breaking down the given information:

- Each caterpillar has I legs.
- There are C caterpillars.
- Casey has 2 legs (since he is a human).

Now, we want to find the total number of legs that the caterpillars and Casey have together.

Step 1: Find the total number of legs that the caterpillars have.
Each caterpillar has I legs, so if we multiply the number of legs per caterpillar (I) by the total number of caterpillars (C), we'll get the total number of legs all the caterpillars have. This gives us the expression:

Total caterpillar legs = C * I

Step 2: Add the number of legs Casey has to the caterpillars' legs.
Casey has 2 legs, so we simply need to add 2 to our previous expression to account for Casey's legs:

Total number of legs = Total caterpillar legs + Casey's legs
Total number of legs = C * I + 2

So the expression for the total number of legs that the caterpillars and Casey have together is:

C * I + 2

This expression represents how to calculate the total number of legs, combining those of the caterpillars and those of Casey.
