To figure this one out, subtract $9.54 from $15, and you'll find that Alice used $5.46 of her credit. Divide this by 14 and you'll get the number of minutes she talked.

First subtract $9.54 from $15.00, this is the amount she spent on the call. Now divide this amount by 14 this will give you minutes she used talking. $15.00 - $9.54 = $5.46. divided by 14 = 39 minutes. 39 X 14 = 5.46. With this card Alice can talk 1 hour 7 minutes. $15.00 divied by 14 = 1.0714285 rounded off to 1.07

To answer this problem requires a two step process…
Step #1
Subtract $9.54 from the cost of the phone card…
$15 - $9.54 = $5.46
Alice’s phone call cost $5.46.
Step #2

$5.46 ÷ $0.14 = 39
Alice’s phone call lasted 39 minutes.

39 minutes
15-9.54=5.46
5.46 / 14 = 0.39
so the answer is 39 minutes

So the equation that the problem gives is this: Let x = minutes of phone call $5.13= $15 - .21x To isolate x, you first subtract 15 from both sides.Your new equation is: -9.87 = -.21x You then divide both sides by -.21. Your new equation is: 47=x
