At a school carnival, each girl received 5 packets of candy canes and each boy received 7 packets of candy canes. Each accompanying adult received 8 packets of candy canes.
29 of the people at the school carnival were adults. The ratio of the number of girls to the number of boys at the carnival was 5 : 8. Given that only 4650 packets of candy canes were given away, how many people were there at the carnival?

79 The number of children is the combined repeated identity. Make the number of children the same. LCM of 13 and 7 is 91.
Number of packets of candy canes given away
= 35 u x 5 + 56 u x 7 + 26 u x 8
= 175 u + 392 u + 208 u
= 775 u
775 u = 4650
1 u = 4650 ÷ 775 = 6
Number of people at the carnival
= 91 u + 26 u
= 117 u
= 117 x 6
= 702
Answer(s): 702
