the manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game. what constant of proportionality relates the number of pretzels to people?\n0.35\n2.86\n35\n140

Answer

Explanation:

Step1: Recall proportion formula

The constant of proportionality $k$ in a proportion $y = kx$ (where $y$ is the number of pretzels and $x$ is the number of people) is given by $k=\frac{y}{x}$.

Step2: Substitute values

We know $y = 7$ (number of pretzels) and $x = 20$ (number of people). So $k=\frac{7}{20}$.

Step3: Calculate the value

$\frac{7}{20}=0.35$

Answer:

0.35
