there are 200 people in total in the audience, assuming that each person receives only one program, 4 packages of 50 programs will be enough because 50 x 4 = 200 and 163+37= 200 and if each person gets 1 program, there are enough programs.
163+ 37 = 200 people
4* 50 = 200 programs
There will be exactly enough programs for every person to get one
