| Total value |
9 u + 882 |
1 u |
10 u + 882 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $9
Number of children = 1 u
Number of adults = 1 u + 98
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 9(1 u + 98) = 9 u + 882
Total cost of all the tickets
= 1 u + 9 u + 882
= 10 u + 882
10 u + 882 = 1132
10 u = 1132 - 882
10 u = 250
1 u = 250 ÷ 10 = 25
Number of child tickets = 25
Answer(s): 25
