Question 1008543
 Matt wants to call his mother long distance. The rate is 80 cents for the first three minutes and 20 cents for each additional minute. How long can he talk for $3.00? 
------
Equation::
Total time = 3min + x(1min)
Value:: 80 + 20x = 300
20x = 220
x = 12 minutes
----
Total time = 3min + 12min = 15 min
