which function rule best describes the relationship between the number of people served and the number of pots of coffee?

$15 each

step-by-step explanation:

$45/3 children= $15 each

b is the correct answer

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the translated point is (5,2)
