The cost of making copies at Store W is ​$6 regardless of the number of copies. The cost of making copies at Store Z is 50¢ per copy plus a ​$1 charge for the use of the machine. The total​ cost, c, of making n copies at either store can be represented by an equation. Write and graph a system to find how many copies you have to make for the cost to be the same at both stores. Use pencil and paper. If you have to make a small number of copies which store should you go​ to? If you have to make a large number of copies which store should you go​ to? Explain. Write the system of equations. Choose the correct answer below.
A.
Store W
c=6
Store Z
c=0.50n−1
B.
Store W
c=0.50n−6
Store Z
c=1
C.
Store W
c=0.50n+1
Store Z
c=6
D.
Store W
c=6
Store Z
c=0.50n+1
