Question

The proportional relationship between the number of sweaters a cothing store buys and sells, s, and the profit, in dollars and cents, that it makes off those sweaters, can be represented by the equation p 238. What is the constant of proportionality from the number of sweaters to the total profit, in dollars and cents?

Answer 1

Proportional relationship formula

$y=kx$

where x and y are the variables, and k is the constant of proportionality.

In this case, the variables are s and p. The equation that relates them is:

$p=23s$

Comparing it with the general formula, the constant of proportionality is:

$k=23$
