Respuesta :
we are given
number of pretzels =y=7
number of people=x=20
now, we have to find
constant of proportionality relates the number of pretzels to people
Let's assume they are directly related
so, we can use formula
[tex] k=\frac{y}{x} [/tex]
where
k is constant of proportionality
y is number of pretzels
x is number of people
so, we can plug values
and we get
[tex] k=\frac{7}{20} [/tex]
so, constant of proportionality is [tex] \frac{7}{20} [/tex]...........Answer
Answer:
0.35.
Step-by-step explanation:
We have been given that the manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game.
We will use proportions to solve our given problem.
[tex]\frac{\text{Number of pretzels}}{\text{Number of people}}=\frac{7}{20}[/tex]
[tex]\frac{\text{Number of pretzels}}{\text{Number of people}}=0.35[/tex]
This means that number of pretzels per people is 0.35, therefore, the constant of proportionality is 0.35.
