Is there a proportional relationship between the number of pounds of apples and their cost? Is there a proportional relationship between the number of toppings on a pizza and its cost? Explain how you know.

The question is incomplete, the complete question is;

Based on the information in the table, is the cost of the apples proportional to the weight of apples?

Pound of apples:

2

3

4

5

Cost of apples:

$3.76

$5.64

$7.52

$9.40

2. Based on the information in the table, is the cost of the pizza proportional to the number of toppings?

Number of toppings:

2

3

4

5

Cost of pizza:

$11.99

$13.49

$14.99

$16.49

See explanation

Step-by-step explanation:

Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.

We know that there is a proportional relationship when there is a linear increase  or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.

In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.

Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
