Answer: The factors are 2, 4 and 13--------------------------------------------------------------------------
5.70c + 9.80a = 1526.60
a = 4c
5.70c + 9.80(4c) = 1526.60
5.70c + 39.20c = 1526.60
44.90c = 1526.60
c = 1526.60/44.90
c = 34 <=== child tickets sold
a = 4c
a = 4(34)
a = 136 ...adult tickets sold
