Question

Using Company A's calling plan, the cost of an overseas phone call is a $0.85 connection fee plus 28 cents per minute. If the total cost of the call is $14.85, how long is the phone call?​

Answer 1

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 2

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
