Question

A high school is having a pancake breakfast fundraiser. they have 3 packages of pancake mix that each feed 90 people. The N(p)=90 represents the number of people N(p) that p packages of pancake mix feed. Find a reasonable domain and range

Answer 1

Let us denote the set of all packages of pancake be P.

Then, $P=[1, 2, 3}$

So, $N(1)=90$

$N(2)=90$

$N(3)=90$

The function can be represented as $N=[(1 ,90),(2 ,90),(3 ,90)]$

Hence, domain = P and range = {90}
