A print company will print business cards for $.10 each plus a setup charge of $12. Another print company offers business cards for $.12 each with a setup charge of $10. What number of business cards will cost the same amount from either printer?

Let the number of cards equal x.

Set up an equation for both companies, set equal to each other and solve for x.

0.10x + 12 = 0.12x + 10

Subtractb0.10x from both sides:

12 = 0.02x + 10

Subtract 10 from both sides:

2 = 0.02x

Divide both sides by 0.02:

X = 2/0.02

X = 100

100 cards would be the same price for both companies.
