If I remember correctly, I believe these ordered pairs indicate a function, as there is exactly 1 output for every input (i.e., (output, input)). If there were 2 inputs of the same number, that'd make this relation not a function.

Given :

A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.

The same meal cost $15 a person with no fee at Good Eats.

To Find :

When does we cater become the better deal.

Solution :

Let , x is number of order .

Cost at cater , C = 12.5x + 30 .

Cost at Good Eats , G = 15x .

We need to find :

G > C

$15x>12.5x + 30\\\\2.5x>30\\\\x>12$

Therefore, after 12th order cater will be more value for money.

Hence, this is the required solution.
