A phone company offers two monthly charge plans. In Plan A, there is no monthly fee, but the customer pays 6 cents per minute of use. In Plan B, the customer pays a monthly fee of $5.10 and then an additional 5 cents per minute of use.

For what amounts of monthly phone use will Plan A cost more than Plan B?
Use M for the number of minutes of phone use in a month, and solve your inequality for M.

I started by creating an inequality but don't know where to go from there.
