At a school carnival, each woman received 5 packets of caramel apples and each man received 7 packets of caramel apples. Each accompanying child received 8 packets of caramel apples.
49 of the people at the school carnival were child. The ratio of the number of women to the number of men at the carnival was 3 : 8. Given that only 2828 packets of caramel apples were given away, how many people were there at the carnival?

59 The number of adults is the combined repeated identity. Make the number of adults the same. LCM of 11 and 5 is 55.
Number of packets of caramel apples given away
= 15 u x 5 + 40 u x 7 + 44 u x 8
= 75 u + 280 u + 352 u
= 707 u
707 u = 2828
1 u = 2828 ÷ 707 = 4
Number of people at the carnival
= 55 u + 44 u
= 99 u
= 99 x 4
= 396
Answer(s): 396
