a grocery store charges $3.02 per milk jug and $0.10 per grocery bag. you never buy the bags because you bring your own. is the total price you pay proportional to the number of milk jugs you buy? choose 1 answer: a yes b no
Answer
Explanation:
Step1: Define variables
Let $x$ be the number of milk - jugs. The cost per milk - jug is $3.02$. The cost of bags is $0$ since you bring your own. So the total cost $y = 3.02x$.
Step2: Check proportionality
The equation $y = 3.02x$ is in the form $y=kx$, where $k = 3.02$ (a constant of proportionality). When $x = 1$, $y=3.02$; when $x = 2$, $y = 3.02\times2=6.04$, and $\frac{y}{x}=3.02$ for all non - zero values of $x$.
Answer:
A. Yes
