Final answer:
To find the constant of proportionality, substitute the values of y and x into the formula y = kx and solve for k. In this case, the constant of proportionality is k = 8.6.
Step-by-step explanation:
To find the constant of proportionality, we can use the formula y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.
Given that y = 137.6 when x = 16, we can substitute these values into the formula and solve for k as follows:
137.6 = k * 16
Divide both sides of the equation by 16:
k = 137.6 / 16
k = 8.6
Therefore, the constant of proportionality is k = 8.6.
