Answer for screen readers
Rachel will need 12 chairs for her birthday party.
Steps to Solve
- Identify the relationship from the table
From the given table, we can observe that there is a consistent ratio between the number of tables and chairs. For every table, there are 6 chairs.
The relationship can be summarized as: $$ \text{Chairs} = 6 \times \text{Tables} $$
- Determine the number of chairs for 2 tables
To find out how many chairs are needed for 2 tables, we use the relationship identified above:
$$ \text{Chairs} = 6 \times 2 $$
- Calculate the total number of chairs
Now, performing the multiplication: $$ \text{Chairs} = 12 $$
Thus, Rachel will need 12 chairs for her birthday party.
Rachel will need 12 chairs for her birthday party.
More Information
This problem demonstrates the use of proportions to determine quantities based on a fixed relationship. Since the number of chairs increases proportionally with the number of tables, knowing the amount for one table allows us to easily scale it to multiple tables.
Tips
-
Forgetting the ratio: Some might overlook the constant ratio of chairs to tables. It's important to remember that each table accommodates 6 chairs.
-
Incorrect multiplication: Double-check calculations to avoid simple arithmetic errors.
