A train ticket in a certain city is $2.00. People who use the train also have the option of puchasing a frequent rider pass for $17.25 each month. With the pass, each ticket costs only $1.25. Determine the number of times in a month the train must be used so that the total monthly cost without the pass is the same as the total monthly cost with the pass.

Without the pass, the rider pays 2.00 * T
With the pass the rider pays 17.25 + 1.25*T
Set the two equal to each other, and solve for T
2.00 * T = 17.25 + 1.25 * T
where T is the number of tickets
