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:
The first first in solving for x is do the distributive property to the left and right of the eqaution. Distribute 2 with 6x and 6. Distribute 3 with x and -4.
Step-by-step explanation:
PEMDAS states that you do things in the parenthesis first.
area of playground= 9×15= 135m^2
area of lawn= 3×4=12m^2
total flooring area= 135-12= 123m^2
cost=36×123=$4428
