Practicing Loops. Einstein Private Elementary school has three classes in each of its 9 grades. 27 classes in total.  It has kindergarten (grade 0) though 8th grade.   The school allows parents to pay tuition over the nine-month school year.  Tuition for kindergarten is $90 dollars every month.  Tuition for the other grades is $50 times the grade level every month.  (1st grade is $50 a month, second grade is $100 a month, etc.) Design a programming solution that outputs nine tuition payment bills for each of the 27 classrooms.  Each bill must contain the grade number (0 through 8), the classroom number (1 through 3), the month (1 through 9) and the amount of the tuition due. Your output should look something like: Grade Classroom Month Tuition   0             1               1        90   0             1               2        90   0             1               3        90   0             1               4        90   ...   8             3               7      400   8             3…
