Let x, y, z be the cost of tickets for ‘under 16 years’, ‘between 16 and 65 years’, and ‘over 65 years’ categories respectively.

$9x + 6y +4z = 162.03$

$7x + 5y +3z = 128.36$

$10x + 4y +5z = 158.50$

Using Graphing Calculator, $x = 7.65, y = 9.85, z = 8.52$

KS Comments:

Straight forward question. Students should address all the variables introduced clearly.
