Kala call lasted for 0.36 minutes
<em><u>Solution:</u></em>
Given that Kala purchased a prepaid phone card for $15
Long distance calls cost $12 a minute using this card.
If the remaining credit on her card is $10.68
To find: Number of minutes her call lasted
Let "x" be the number of minutes her call lasted
Cost of 1 minute = $ 12
Total balance = $15
Remaining balance = $ 10.68
So we can frame a equation as:
Total balance = Remaining balance + Cost of 1 minute x number of minutes her call lasted

So her call lasted for 0.36 minutes
Answer:
y = At²/755
Step-by-step explanation:
A = 755y/t²
multiply both sides by t²
At² = 755y
Divide both sides by 755
At²/755 = y
Flip
y = At²/755
