79 The number of adults is the combined repeated identity. Make the number of adults the same. LCM of 13 and 7 is 91.
Number of packets of candy canes given away
= 35 u x 4 + 56 u x 5 + 26 u x 7
= 140 u + 280 u + 182 u
= 602 u
602 u = 3612
1 u = 3612 ÷ 602 = 6
Number of people at the carnival
= 91 u + 26 u
= 117 u
= 117 x 6
= 702
Answer(s): 702
