At a local print shop, 12 copies can be made for $3. At this rate, how much would it cost to make 84 copies? Fill out the table of equivalent ratios until you find a value of x. But i don't get it i divided 21 but got 4/7 & 1/7 so do i multiply or what

$21

It would cost $21 to make 84 copies

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
