Printer A prints business cards for $.10 each plus a setup charge of $15.
Printer B offers business cards for $0.15 each with a set up charge of $10.
What number of cards would make the cost the same at either printer?
Let x be the number of cards that would make the cost the same at either printer.
For Printer A:
Cost = 0.10x + 15
For Printer B:
Cost = 0.15x + 10
Setting the two costs equal to each other:
0.10x + 15 = 0.15x + 10
Subtracting 0.10x and 10 from both sides:
5 = 0.05x
Dividing by 0.05 on both sides:
x = 100
Therefore, 100 cards would make the cost the same at either printer.
