Question

the unruly queens chess club is hosting a tournament, and each club member is bringing something to eat or drink. valentina decides to bring oatmeal raisin cookies from her favorite bakery. this table shows the relationship between the number of oatmeal raisin cookies valentina buys, x, and their total cost (in dollars), y. x (cookies) 8 24 27 41 y (dollars) $24 $72 $81 $123 according to the values in the table, do x and y have a proportional relationship? yes no

Explanation:

Step1: Calculate the unit rate for each pair

For the first pair: \(\frac{24}{8} = 3\)
For the second pair: \(\frac{72}{24}=3\)
For the third pair: \(\frac{81}{27} = 3\)
For the fourth pair: \(\frac{123}{41}=3\)

Step2: Check if the unit rate is constant

Since for all pairs \(\frac{y}{x}=3\) (constant)

Answer:

yes
