# 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.
