The constant of proportionality for the ratio of price to the number of bouquets is 3.
What is constant of proportionality?
"The constant of proportionality is the ratio between two directly proportional quantities."
The formula to calculate the constant of proportionality:
The constant of proportionality 'k' for two quantities x, y is, k = y / x
For given situation,
Number of Bouquets has values 3, 6, 9, 12 and the column Price (dollars) has values 9, 18, 27, 36.
Let x represents the number of bouquets and y represents price.
From the table given below we can observe that the number of bouquets is directly proportional to price(dollars).
As the number of bouquets increases, price also increases.
So, the ratio of price to the number of bouquets would be y/x.
9/3 = 3
18/6 = 3
27/9 = 3
36/12 = 3
This means, the ratio of price to the number of bouquets is constant.
So, the constant of proportionality, k = 3
