your cellular phone plan costs $11 per month plus $.12 per minute of phone usage.you want to pay no more then $20 per month.What are the most number of minutes (m) that you can allow for phone calls each month?
$20 - $11 = $9
$9 / .12 = ?
If paid 30.00 for A phone card and every minute cost 21cent aminute how How many Minutes do u have
To find the most number of minutes you can allow for phone calls each month while paying no more than $20, we can set up an equation:
Total cost = $11 (fixed monthly cost) + (.12) (cost per minute of usage) * (number of minutes)
We want the total cost to be less than or equal to $20.
Therefore, the equation becomes:
11 + 0.12m ≤ 20
To solve for m, we can subtract 11 from both sides of the inequality:
0.12m ≤ 20 - 11
0.12m ≤ 9
Finally, divide both sides of the inequality by 0.12:
m ≤ 9 / 0.12
m ≤ 75
Therefore, the most number of minutes (m) that you can allow for phone calls each month while paying no more than $20 is 75 minutes.
