Question

2) Leah is buying pizza for her birthday

party. She has $48 to spend on pizza
and each pizza costs $8. Letx
represent the number of pizzas she
purchases, and let y represent the
total cost. (Hint: Create a table first.)
Domain:
Range:

Answer 1

Explanation:

To determine the domain and range in this scenario, let's create a table to understand the relationship between the number of pizzas purchased (x) and the total cost (y):

x (Number of pizzas) | y (Total cost)

---------------------|--------------

1 | 8

2 | 16

3 | 24

4 | 32

5 | 40

6 | 48

The domain represents the set of possible values for the independent variable, which in this case is the number of pizzas (x). From the table, we can see that the number of pizzas can range from 1 to 6. Therefore, the domain is {1, 2, 3, 4, 5, 6}.

The range represents the set of possible values for the dependent variable, which in this case is the total cost (y). From the table, we can see that the total cost can range from $8 to $48. Therefore, the range is {$8, $16, $24, $32, $40, $48}.

In summary:

Domain: {1, 2, 3, 4, 5, 6}

Range: {$8, $16, $24, $32, $40, $48}

This means that Leah can purchase any whole number of pizzas between 1 and 6, and the total cost will be one of the corresponding values listed in the range.
