Question

The function c = 2.50(n – 2) + 1.50 represents the cost c in dollars of printing n invitations. Which of the following is not true?
A For each additional invitation, it costs an extra $2.50 to print.
B Each invitation costs $1.50 to print
C One can not print just one invitation.
D The cost depends on the number of invitations printed.

Answer 1

B: Each invitation costs $1.50 to print

Answer 2

Answer:

Option B -  Each invitation costs $1.50 to print

Step-by-step explanation:

Given : The function $c=2.50(n-2)+1.50$

 Where,

 n: number of invitations

 c: cost in dollars

 The slope of the line for this case is: $m=2.50$

 The slope represents the cost of printing of each of the invitations.

 Therefore, it is false that the cost of printing of each invitation is $ 1.50

So, Option B is not true

i.e, B- Each invitation costs $1.50 to print
