Adults [———————–5u——————-]
[——- 5/8 < 60yo —-][3/8 >=60yo]
Children [– u—]
(a) [(3/8)(5u)] / 6u = (15/8) u / 6u = 15/48 = 5/16
Hence fraction of tickets sold for adults 60 and above is 5/16
(b) (5/8)(5u)(16) + (3/8)(5u)(11) +7u = 5589 <——— x 8 on both sides
400u + 165u +56u = 44712
621u = 44712
u = 72
Total tickets sold = 6u = 6 x 72 = 432
