Question

Solve the problem.

When making a long distance call from a certain pay phone, the first three minutes of a call cost $2.95. After that, each additional minute or portion of a minute of that call costs $0.20. Use an inequality to find the number of minutes one can call long distance for $6.95.
A) 23 minutes or fewer
B) 35 minutes or fewer
C) 20 minutes or fewer
D) 2 minutes or fewer

Answer 1

$6.95 - $2.95 = $4
.2m ≥ 4
-> m ≥ 4/.2 = 20 min

Answer 2

$6.95 - $2.95 = $4 ( first 3 min)
.2m ≤ 4
-> m ≤ 4/.2 = 20 min
Thus 3 + less than 20 = ...
