Question

The function c = 2.50(n – 2) + 4.50 represents the cost c in dollars of printing n invitations. Which of the following is not true?

a.One cannot print just one invitation.

b.For each additional invitation, it costs an extra $2.50 to print.

c.Each invitation costs $4.50 to print.

d.The cost depends on the number of invitations printed.

Answer 1

c.Each invitation costs $4.50 to print.

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.

Answer 2

The answer is B, I think.
