One long-distance telephone company offers a plan such that the first 20 minutes costs $.99 and each additional minute costs $.09. Solve an inequality to find the maximum amount of full minutes you can talk for $5.00.

At first I got: 5 is greater than or equal to .99+(1.8-.09m)

But that's not right because i solved it and got a negative number and you can't talk for negative minutes
