11 u + 580 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $10
Number of children = 1 u
Number of adults = 1 u + 58
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 10(1 u + 58) = 10 u + 580
Total cost of all the tickets
= 1 u + 10 u + 580
= 11 u + 580
11 u + 580 = 877
11 u = 877 - 580
11 u = 297
1 u = 297 ÷ 11 = 27
Number of child tickets = 27
Answer(s): 27
