Answer:
The total cost C = $10 + $0.05·x
Step-by-step explanation:
The given parameters are
The cost of the cell phone plan per month = $20
The number of minutes of free calls that one can make in a month = 200 minutes
The cost of additional minutes of cell phone call = 5 cent
5 cents to a dollar = $0.05
The total number of minutes of calls made in a month = x
The time duration of a person's usage of the cell phone in a month > 200 minutes
The total cost C of a person's usage per month is given by;
C = $20 + $0.05 × (x - 200) = $20 + 0.05·x - $10
C = $10 + $0.05·x
Where x > 200.
Answer:
4 : 25 to round off we have to see that
4 : 25 to round off we have to see that If in ones place it is more than 5 or not
4 : 25 to round off we have to see that If in ones place it is more than 5 or not if yes we will add to 1 no to tenths place
4 : 25 to round off we have to see that If in ones place it is more than 5 or not if yes we will add to 1 no to tenths place Finally 4 : 25 it has 5 in its ones place
<h3>
<em><u>So the answer will be 4 : 30</u></em> </h3>
You would have to move terms which will bring you to 14.4 x - 19.2 = 19.2 - 4.8x the you would combine like terms then you would get 19.2x= 38.4 then you divide both sides by 19.2 and get 2 as your answer.
go to the link the person took and you’ll get the answer i believe.
