Answer:
Step-by-step explanation:
100 Let x = adult ticket
y = student ticket
6x + 12y = 186 ----------(i)
11x + 6y = 197 -----------(ii)
(i) 6x + 12y = 186
(ii)*2 22x + 12y = 394
(-) (-) (-)
subtract (ii) from(i) -16x = -208
x = -208/-16
x = 13
x = 13 in equation (i)
6*13 +12y = 186
78 + 12y= 186
12y = 186 - 78
12y = 108
y= 108/12
y = 9
Price of an adult ticket = $13
Price of a student ticket = $9
