Using a Table to Find the Constant of Proportionality This table represents a proportional relationship. Use the table to identify the constant of proportionality between the ratio of the number of laps to the number of swimmers.

The constant of proportionality is .

Step-by-step explanation:            

                                                         associated y value (from any line of table)

The constant of proportionality is                      

                                                                         one specific x value

Example:  If y = 5 when x = 2, then the constant of proportionality is

         5

k =

          2

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
