Studdy Solution

STEP 1

1. Liz sets up 6 rows of 4 chairs each.
2. Shen states that there are 2 fewer chairs than needed.
3. We need to find the total number of chairs required.

STEP 2

1. Read the problem and understand the given information.
2. Draw a representation of the situation.
3. Write an equation to find the total number of chairs needed.

STEP 3

Read the problem and understand the given information.
Liz sets up 6 rows of 4 chairs, which means she sets up a total of 6×4 6 \times 4 chairs. Shen mentions that this is 2 fewer than needed.

STEP 4

Draw a representation of the situation.
Imagine a grid with 6 rows and 4 columns, representing the chairs Liz set up. This visual helps us see that Liz set up 6×4=24 6 \times 4 = 24 chairs.

STEP 5

Write an equation to find the total number of chairs needed.
Since Shen says there are 2 fewer chairs than needed, we can write the equation:
Chairs set up+2=Chairs needed \text{Chairs set up} + 2 = \text{Chairs needed}
Substitute the number of chairs set up:
24+2=Chairs needed 24 + 2 = \text{Chairs needed}

STEP 6

Calculate the total number of chairs needed.
Chairs needed=24+2=26 \text{Chairs needed} = 24 + 2 = 26
The total number of chairs they need is:
26 \boxed{26}
