C. 9, 18, 27, 36, 45

D. 10, 20, 30, 40, 50

Answer 1

The independent variable is the number of sweatshirts sold so it is answer A.

(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)

Answer 2

A) 1, 2, 3, 4, 5

Explanation:

The graph shows the number of Sweatshirts sold and amount of money raised.

Here x-axis represents the number of Sweatshirts sod and y-axis represents the amount of money raised.

From the given graph, we infer cost of 1 Sweatshirt is $9.

2 Sweatshirts = $ 18

3 Sweatshirts = $27

4 Sweatshirts = $36

5 Sweatshirts = $45

Here the amount of money depends upon the number of Sweatshirts sold.

Here the number of Sweatshirts sold represents the independent variable and the amount of money raised represents the dependent variable.

So, independent quantities = 1, 2, 3, 4, 5.

Therefore, answer is A) 1, 2, 3, 4, 5
