Two tailors, Miranda and Paula, sit down to do some embroidery. Miranda can embroider 5
shirts per hour, and Paula can get through 6 shirts per hour. In addition, the tailors had
previously finished some shirts. Miranda has already completed 14 shirts, and Paula has
completed 6 shirts. Miranda and Paula decide to take a break when they have finished the
same total number of shirts. How many shirts, in total, will each tailor have finished? How
long will that take?
