To find the constant of proportionality, we can use the formula:
constant of proportionality = (change in dependent variable) / (change in independent variable)

Let's calculate the changes in price and amount of coffee:
Change in price = 30.00 - 7.50 = 22.50
Change in amount of coffee = 4 - 1 = 3

Now, we can find the constant of proportionality:
constant of proportionality = 22.50 / 3 = 7.50

Therefore, the constant of proportionality is 7.50.
