The senior class is going on a field trip to the Science Museum, where they will

spend the day and see a great 3-D IMAX movie. The museum offers a schoolgroup price of $189, and the students will each pay an equal part of that total.When rainy weather caused a baseball game to be rescheduled for the day of thefield trip, 12 of the students had to miss the trip to play in the game. As a result,each student who went to the movie paid one dollar more than they would have if the baseball playershad gone, too.

How many students went on the field trip?

How much did each student pay?
