Describe the situation with a linear inequality and then solve the inequality.A standard train ticket in a certain city costs 
per ride. People who use the train also have the option of purchasing a frequent rider pass for 
each month. With the pass, a ticket costs only
per ride. Use an inequality to determine the number of train rides in a month for which purchasing the monthly pass is more economical than purchasing the standard train ticket.
