Best ResponseYou've already chosen the best response.11 minute costs 6 cents 2 minutes cost 2 * 6 cents = 12 cents 3 minutes cost 3 * 6 cents = 18 cents What about 5 minutes?

Best ResponseYou've already chosen the best response.1Right. At the rate 6 cents per minute, a 5minute call would cost 30 cents. Now lets; read carefully the problem.

Best ResponseYou've already chosen the best response.1The problem states: "A long distance telephone company charges a rate of 6 cents per minute or a 50cent minimum charge per completed call, whichever is greater."

Best ResponseYou've already chosen the best response.1From this part: "A long distance telephone company charges a rate of 6 cents per minute" you'd have a 30cent charge for a 5minute call, but from this part: "... or a 50cent minimum charge per completed call, whichever is greater." you see that the company will never charge you less than 50 cents for any call. Since a 5minute call is only 30 cents, the company charges the 50cent minimum for it. That means a 5minute call really costs 50 cents. Do you understand this?

Best ResponseYou've already chosen the best response.0but its 50 cents minimum charge per completed call

Best ResponseYou've already chosen the best response.1Right. That is why even though this call should have cost 30 cents, it really costs 50 cents. Any call that costs less than 50 cents has its price raised to 50 cents because of the 50cent minimum charge the company has.

Best ResponseYou've already chosen the best response.1A great question. We needed to see if the charge was going to be the actual cost of the call or the minimum 50cent charge. We needed to see whether 5 minutes at 6 cents per minute would by more or less than the 50cent minimum. Once we multiplied 5 * 6 and got 30 cents, now we know we use the minimum charge and not eh 30cent charge.

Best ResponseYou've already chosen the best response.1We're getting there. Now that we know the charge is 50 cents for a 5 minute call, we finish the problem.

Best ResponseYou've already chosen the best response.1Since the 5minute call really cost 50 cents, now we can find the cost per minute for the 5minute call: \(cost ~per ~minute = \dfrac{cost ~of ~the ~call}{number ~of ~minutes}\) \(cost ~per ~minute = \dfrac{50~cents}{5~minutes}\) What is 50/5 = ?

Best ResponseYou've already chosen the best response.050/5=10 @mathstudent55

Best ResponseYou've already chosen the best response.1Right. A 5minute call costs 50 cents, and since 50 cents/5 minutes = 10, it costs 10 cents per minute.
