The unruly queens chess club is hosting a tournament, and each club member is bringing something to eat or drink. nicole decides to bring oatmeal raisin cookies from her favorite bakery.

there is a proportional relationship between the number of oatmeal raisin cookies nicole buys, x, and their total cost (in dollars), y.

x (cookies) y (dollars)

10 $ 10

12 $ 12

14 $ 14

20 $ 20

write an equation for the relationship between x and y.

y=?

The required equation is y=x.

Step-by-step explanation:

The given data table is

x (cookies)     y (dollars)

   10                    $ 10

   12                    $ 12

   14                    $ 14

   20                   $ 20

It is given that there is a proportional relationship between the number of oatmeal raisin cookies Nicole buys, x, and their total cost (in dollars), y.

The value of y is 10 and x=10, so

Divide both sides by 10.

The value of k is 1.

The equation for the relationship between x and y is

Therefore, the required equation is y=x.
