Step-by-step explanation:

Answer 2

Answer:

c.Each invitation costs $4.50 to print.

Step-by-step explanation:

Based on the equation, since we subtract 2 from n before multiplying by 2.50, this means we cannot print fewer than 2 invitations.  A is true.

Multiplying the number of invitations by 2.50 shows us that it costs an extra 2.50 per invitation to print.  B is true.

Since it costs 2.50 per invitation to print, it does not cost 4.50 per invitation to print.  C is not true.

The cost does depend on the number of invitations printed; D is true.
