Let's Say You Have a Choice Between Two Checking Plans

Multiple Choice

Let's say you have a choice between two checking plans. With the first plan, you will be charged $ 3 per month plus 25 ¢ per check. With the second plan, you will be charged $ 4 per month regardless of how many checks you write. If you write only a few checks, the first plan is clearly cheaper. Similarly, if you write many checks a month, the second plan is clearly cheaper. Determine the number x that will enable you to make the following statement: If you write 1 to x checks per month, choose the first plan. If you write more than x checks per month, choose the second plan. ​

A) x = 8
B) x = 10
