A person makes an overseas phone call. The telephone company charges 65 cents for the first minute and then 75 cents for each minute thereafter. Because it's an overseas phone call, there is also a 55 cent service charge. If the phone call cost $ 19.20 , how many minutes did this person talk?

25 minutes.

Step-by-step explanation:

A person makes an overseas call.

The telephone company charges 65 cents for the first minute.

Then 75 cents for each minute thereafter.

There is a 55 cent service charge.

1 dollar = 100 cents

65 cents = $0.65

75 cents = $0.75

55 cents = $0.55

For a phone call that cost $19.20 ;

Subtracting the service charge and the first minute charge from overall cost we get;

$19.20 - $0.55 - $0.65 = $18

For every additional minute there is a charge of $0.75

How many minutes make $18 ;

Cross multiplying this gives;

= 24  minutes.

So the call lasted 24 minutes + 1 minute = 25 minutes.
