Question

practice: more comparison word problems
marcus goes down 6 waterslides.
hailey goes down 4 fewer waterslides than marcus.
how many waterslides does hailey go down?
which model can be used to solve the problem?
first model: marcus (2 blue, 4 orange circles); hailey (2 blue circles)
second model: marcus (6 blue circles); hailey (10 blue circles)

Explanation:

First, solve the number of waterslides Hailey goes down:

Step1: Identify Marcus' slides

Marcus goes down 6 waterslides, so we have the number \( 6 \).

Step2: Calculate Hailey's slides

Hailey goes down 4 fewer than Marcus. To find Hailey's number, we subtract 4 from Marcus' number. The formula is \( 6 - 4 \).
\( 6 - 4 = 2 \)

Marcus has 6 slides. Hailey has 4 fewer, so Hailey's count should be less than Marcus'. The first model shows Marcus with 6 (2 blue + 4 orange, but the blue part for Hailey is 2, matching \( 6 - 4 = 2 \)). The second model shows Hailey with more slides, which is incorrect. So the first model (with Marcus having 6 circles and Hailey having 2 circles) is correct.

Answer:

Hailey goes down 2 waterslides.

Now, determine the correct model:
