The cost for a long-distance telephone call is $0.36 for the first minute and $0.40 for each additional minute or portion thereof. Write an inequality representing the number of minutes a person could talk with out exceeding $3.00
-------------
Let # of minutes of calling be "x".
Cost(x) = 0.36 + (x-1)0.40
INEQUALITY:
0.36 + (x-1)*0.40 <=3
36 + 40(x-1) <= 300
40x-4 <= 300
40x <= 304
x<=7.6 minutes
