What is the average amount of salt called for in each recipe?

The answer is 3.5

To find the average of a set of numbers, add them together then divide the result by how many numbers there were.

To find the average of 4, 4, 4, and 2, add them: 4+4+4+2=14. There were 4 numbers. Divide 14 by 4: the answer is 3.5

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
