At a school carnival, each woman received 5 packets of candy canes and each man received 6 packets of candy canes. Each accompanying child received 7 packets of candy canes.

47 The number of adults is the combined repeated identity. Make the number of adults the same. LCM of 9 and 4 is 36.
Number of packets of candy canes given away
= 16 u x 5 + 20 u x 6 + 27 u x 7
= 80 u + 120 u + 189 u
= 389 u
389 u = 1167
1 u = 1167 ÷ 389 = 3
Number of people at the carnival
= 36 u + 27 u
= 63 u
= 63 x 3
= 189
Answer(s): 189
