The proportional relationship that gives the rule for finding the number n of bagels in any number b of scores is:
n = 0.05b.
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For this problem, we want to number n of bagels in b scores, hence the format of the relation is:
n = kb.
The number is 1/20 of the scores, hence the constant is k = 1/20 = 0.05 and the equation is:
n = 0.05b.
