At Esme's school, there are 30 teachers and 45 staff members. On a Monday morning, The Best Pizza Inn brought pizza for the staff and teachers as a promotion offer. If 2/3 of the teachers and 4/5 of the staff members ate Pizza, how many non-pizza eaters are at Esme's school?
The total number of teachers who ate pizza is 2/3*30 = <<2/3*30=20>>20
30-20 = <<30-20=10>>10 teachers did not eat pizza.
The number of staff members who ate pizza is 4/5*45 = <<4/5*45=36>>36
The number of staff members who did not eat pizza is 45-36 = <<45-36=9>>9
The number of non-pizza eaters is 9+10 = <<9+10=19>>19
