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:
1st statement is true.
2nd statement is false.
3rd statement is true.
Step-by-step explanation:
We have been given two inequalities and we are asked to find out whether the given statements are true or false.
represents balance of account A and 
represents balance of account B.
1. We can see from our inequalities that Jeremiah initially invested $100 in account A and $50 in account B. Therefore, 1st statement is true.
2. The rate at which balance of account A grows is 1.2 and rate for account B is 1.23. Therefore, 2nd statement is false.
3. We can find total amount Jeremiah invested in two accounts by adding initial investment of both accounts, that is 100+50=150 . Therefore, 3rd statement is true.
If you want midpoint it would be (2,5)
If you want endpoint it would be (5,8)
