Which equation represents the proportional relationship in the table ?

2 answers:

6 0

The answer is c = 3r. Note that c is the output and r is the input. I figured this out by using mental math and noticing the pattern. Each value the input is multiplied by 3, which results in the output.

(INPUT)2 * 3 = 6 (OUTPUT)
(INPUT)4 * 3 = 12 (OUTPUT)
(INPUT)7 * 3 = 21 (OUTPUT)
(INPUT)10 * 3 = 30 (OUTPUT)
(INPUT)12 * 3 = 36 (OUTPUT)

Step-by-step explanation:

Reason is, adult tickets and child tickets are two different things, so they require two different variables, and two different equations because they have two different sums. (This was probably already obvious to you though).

Hope this helps :)

I tried my best to explain.
