Question

Solve the direct variation problemsJohn is working at a bank and receives 25 dollars an hour. a. Write an equation that relates x and y.b. what is the constant of proportionality?

Answer 1

Let "x" represent the number of hours that John works and "y" represent John's earnings after working x hours.

b) John receives $25/hour → this value represents the change in John's earnings for every unit increase of x, which is, the constant proportionality (k) of the relationship.

a) If x and y have a direct relationship, you can express it as follows:

`y=25x`
