2012 A-level H2 Mathematics (9740) Paper 1 Question 1 Suggested Solutions

All solutions here are SUGGESTED. Mr. Teng will hold no liability for any errors. Comments are entirely personal opinions.

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.
