Question

Answer

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
