Hi, can anyone assist me with my son's P5 Maths concept exercise?

Q5. A business class air ticket to Malaysia cost \$250 and an economy class air ticket cost \$160.There were twice as many economy class tickets than business class tickets were booked. The amount collected from the sale of all economy class tickets was \$4200 more than the sale of all business class. How much was the total sale of all the tickets sold?

Thanks and best regards!

Gday Rohana,

Following pls find my worked solution:

Number of tickets sold/booked:
E : B
2 : 1

Sales of tickets:
E: 2u × 160 = 320u
B: 1u × 250 = 250u

Given the total sales from E tickets was \$4200 more than that of B tickets, we have ...

320u - 250u = 4200
70u --> 4200
1u --> 60

Hence, total sales = 320u + 250u = 570u
570u --> 570 × 60 = \$34200

===========

Trust this helps.

Do let me know again if this is different from your Answerkey or if there's further clarification.

Cheers,
Edward
