Question

as a seismologist, tracy understands the devastating effects that earthquakes can have. so, she keeps her basement stocked with canned food, like chili. tracy buys cans of chili from an online retailer that charges a shipping fee plus the cost of each can of chili. this table shows the relationship between the number of cans of chili tracy buys, x, and the total cost (in dollars), y. x (cans) y (dollars) 20 $33.80 40 $59.60 50 $72.50 60 $85.40 according to the values in the table, do x and y have a proportional relationship? yes no

Explanation:

Step1: Check proportionality via ratio $\frac{y}{x}$

For $x=20, y=33.80$: $\frac{33.80}{20}=1.69$
For $x=40, y=59.60$: $\frac{59.60}{40}=1.49$
For $x=50, y=72.50$: $\frac{72.50}{50}=1.45$
For $x=60, y=85.40$: $\frac{85.40}{60}\approx1.423$

Step2: Compare the calculated ratios

The ratios $\frac{y}{x}$ are not equal across all pairs.

Answer:

no
