The cost for a long distance phone call is 0.46 for the first minute,and 0.21 for additional minute or portion thereof.Write an inequality representing the number of minutes a person could talk without exceeding 3.00
Let "x" be the number of minutes of talk.
EQUATION:
Cost = 0.46 + (x-1)0.21
You want cost <-3.00
INEQUALITY:
0.46 +0.21(x-1)<=3.00
