Respuesta :
163+ 37 = 200 people
4* 50 = 200 programs
There will be exactly enough programs for every person to get one
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.
