Question

the unruly queens chess club is hosting a tournament, and each club member is bringing something to eat or drink. leslie decides to bring oatmeal raisin cookies from her favorite bakery. there is a proportional relationship between the number of oatmeal raisin cookies leslie buys, x, and their total cost (in dollars), y. write an equation for the relationship between x and y. simplify any fractions. y =

Explanation:

Step1: Recall proportional - relationship formula

The equation for a proportional relationship is $y = kx$, where $k$ is the constant of proportionality.

Step2: Find the constant of proportionality $k$

We can use a point on the line. Let's take the point $(5, 6)$. Substitute $x = 5$ and $y = 6$ into $y=kx$. Then $6 = k\times5$, so $k=\frac{6}{5}$.

Step3: Write the equation

The equation for the relationship between $x$ and $y$ is $y=\frac{6}{5}x$.

Answer:

$y=\frac{6}{5}x$
