Question 928588: One checking plan charges $3 per month plus .12 cents per check. Another plan charges 24 cents per check. For how many checks per month are the costs of the two plans the same?

You can put this solution on YOUR website! x = number of checks per month
---
plan A:
y = 0.12x + 3
---
plan B:
y = 0.24x
---
the costs of the two plans are equal when:
0.12x + 3 = 0.24x
0.24x - 0.12x = 3
(0.24 - 0.12)x = 3
x = 3/(0.24 - 0.12)
x = number of checks per month = 25
