Step-by-step explanation:
7/9 x 27 - 18 + 1/3 x 27
Express 7/9 ×27 as a single fraction.
7 x 27 / 9 - 18 + 1/3 x 27
Multiply 7 and 27 to get 189.
189/9 - 18 + 1/3 x 27
Divide 189 by 9 to get 21.
21 - 18 + 1/3 x 27
Subtract 18 from 21 to get 3.
3 + 1/3 x 27
Multiply 1/3 and 27 to get 27/3.
3 + 27/3
Divide 27 by 3 to get 9.
3+9
Add 3 and 9 to get 12.

Answer:
child tickets: 115
adult tickets: 175
Step-by-step explanation:
number of child tickets = x
number of adult tickets = y
(value of child ticket [8] * number of child tickets [x]) + (value of adult ticket [8.5] * number of adult ticket [y]) = total value (2407.50)
8x + 8.5y= 2407.50
290 (total number of tickets) = x (number of child tickets) + y (number of adult tickets)
290 = x+y
system of equations: 8x + 8.5y= 2407.50
290 = x + y
solve equation:
x = 115
y = 175
