<PRE><B>Question 778484</B>
When you contacted the Talks-A-Lot company, they were offering a monthly of $40 for 500 minutes and $0.25 for each minute over the 500 minutes. 
A(x) = 40 + 0.25(x-500)
----------------------------------

In the sunday paper you see an ad for ChatAway company, which offers a monthly plan of $35 for 500 minutes and. $0.30 for each minute over the 500 minutes.
C(x) = 35 + 0.30(x-500)
----------------------------------


 How many minutes would you have to talk over the 500 minutes for the cost to be the same with both companies? What would be the equal cost?
--------
Solve for &quot;x&quot;:
40+0.25(x-500) = 35+030(x-500)
--------
5 = 0.05(x-500)
--------
100 = x-500
---------
x = 600 minutes is the break-even # of minutes.
-------------
A(600) = 40+0.25(600-500)
A(600) = 40+25 = $65
