explain ur thinking!

Answer and Step-by-step explanation:

If we order 3 turkey sub

$20/3 =  $6.66 per turkey sub

If we order 4 turkey subs, the order would be

$26/4 =  $6.5 per turkey sub

If we order 4 turkey subs, we get a price reduction per turkey sub.

So the relationship between the number of turkey subs ordered and the price is not proportional (linear)

We know this because as the order increases, we do not have the same cost per turkey sub.

$6.66 ≠ $6.5

If you order 3 turkey subs, you will pay $20 dollars or $6.66 per turkey sub

If you order 4 turkey subs, you will pay $26 dollars or $6.5 per turkey sub

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
