The company charges a flat rate of $25 per month in addition they charge $0.05 for each minute of service.
A.write a linear equation for the monthly charge based upon the numberof minutes of service each month.
C(x) = 0.05x + 25
---------
B.what is the slope?:: 0.05
----------
C.what is the y-intercept?:: 25
-----------
D.what would be the charge for 100 minute of service?
C(100) = 0.05*100 + 25 = 5+25 = $30
------------------
E.You Can afford a $55 phone bill each month. How long can you afford to talk on the phone each month?
Solve:
0.05x + 25 = 55
0.05x = 30
x = 3000/5
x = 600 minutes
