The amount raised is the dependent variable and the number of shirts sold is the independent variable.
Answered by GPT 3.5
The constant of proportionality can be found by taking the ratio of the amount raised to the number of shirts sold.

For example, for the first data point (1 shirt sold, $4 raised), the ratio is 4/1 = 4.

Similarly, for each data point, the ratio is:

Second data point (2 shirts sold, $8 raised): 8/2 = 4
Third data point (3 shirts sold, $12 raised): 12/3 = 4
Fourth data point (4 shirts sold, $16 raised): 16/4 = 4

The constant of proportionality in this case is 4. This means that for every shirt sold, the amount raised is multiplied by 4.
