Answer:

50 min

Explanation:

Let the call be for x minutes

14.85 = 0.85 + 0.28x

0.28x = 14

x = 14/0.28 = 50

Answer:

50 minutes

Explanation:

28 cents = $0.28

Let the call be for x minutes

Total cost = connection fee + x*cost per minute

14.85 = 0.85 + 0.28x

14.85 - 0.85 = 0.28x

0.28x = 14

x = 14/0.28

x = 50
